Economics 19/06/2010: Ideas that (allegedly) will change the world 1

Forbes Magazine has published a list of 25 ideas that will change the world in the 21^st century. The list is available here. Let's take a look. Some are quite interesting, others are banal...

I’ll be blogging about it over the next few days.

Number 1.
"In coming years, increasingly larger amounts of capital will come into the financial system. ...India, China and a few other developing economies will attract a much larger portion of foreign savings. …This increased flow of capital presents us with a unique opportunity to transform [Indian] society. …the financing, investment and risk management needs of companies and governments are growing in size and complexity, and financial institutions should have the ability to support this growth.”

[So far, nothing new – investment into Brics has been growing steadily and the trend is likely to continue for some time assuming:

1. Massive Government-fuelled credit and spending expansion in China continues
2. Massive Government spending-fuelled expansion in Brazil continues (for the record – Brazil’s fiscal deficit is reaching beyond 13% per annum at the time of rapid economic growth – if one ever had a more pro-cyclical fiscal policy than that and didn’t end up in ditch afterward, do let me know)
3. India can supply significant translation of internal growth into external and expatriable revenue for companies without either running a massive inflation or grinding to a halt on the back of collapsed exports demand
4. Russia returns to robust growth – though in the case of Russia, there is little chance the country does not really attract massive external funding outside extraction industries.

But the thing about these countries swallowing a greater share of Western savings is probably true, for some time. Not sure if it will last through the 21^st century]

“Technology will play an important part in this transformation, because it has the ability to break access barriers and bring down transaction costs to a fraction of what they are today. …One such transformational change will come from mobile payment systems.” [An interesting, but not very ‘futuristic’ view – the view that few would disagree with]

“Technology will enable Mutual Funds to sell and service much smaller investment units and insurance companies to sell much smaller policies than they are able to do now. [Alas, mutual funds industry is hardly a cutting edge stuff. Especially since ETFs offer much more at much lower costs. And they do not need any new technology to offer their services to smaller investors] …Similarly, processing small loans and small insurance claims will become faster and easier... Databases with credit histories, and Unique Identification systems will allow financial institutions to reduce risk when they make loans or provide other financial services.” [I am not sure that risk management is a matter of technology bottlenecks. While computational and data processing power can help, it can’t alleviate the problems of modelling and pricing risk, or the problems relating to catastrophic risks, or the much more salient – from Bric’s perspective – problem of basic individual risks inherent in the client base. Machines might change the modes of analysis, but they can’t change the default probabilities of people.]

“The impact of technology is not limited to retail financial services alone. At the core of the financial system where equity, credit, currency and other risks are traded, we need deep, liquid and resilient markets. Technology is helping these markets enormously, and playing an important role in improving efficiency of capital allocation and risk management.” [Yes, but… the speed of order systems in world’s leading exchanges is now so much faster than the speed at which information is delivered to the public and even recorded, that we have clearing and disclosure systems operating at slower speeds than booking systems. It is a serious concern]

[I am not really convinced the idea of India’s and emerging markets financial revolution is… well… all together so revolutionary. Looks like a simple linear projection of a trend.]



Number 2: the emergence of non-English language based cultures on the web.

“…culture does get transmitted; the early adopters, eagerly working on the [African languages] Internet, say, will also be speaking English or French, and they will transmit best practices. It won't take as long as it did the first time. …You already have the 3G mobile network so basically you just need a device to connect. The questions are what devices they will use to connect and when those devices will become affordable. Like with telephony, where people who have never had a landline leap straight to mobile phones, we will see people who have never had an Internet connection leap straight to broadband.”

[An interesting point, but again, hardly revolutionary. In fact, most of hardware referred to above is clearly already in place or being put into action. Its price is collapsing rapidly, including in emerging economies. African consumers of mobile data are pretty much identical in their patterns of consumption to those in the West or Asia. The question is about ‘software’ of culture, of language. A person, say in Africa, can opt for the use of a local language and local culture, drawing on few thousands in terms of potential market for their ideas and content. Or the same person can opt for English or French or Spanish or Chinese. Foreign language merging with foreign culture will not only open the culture up to a larger scale market, but it will also lead to more interesting interaction between language and culture, potentially leading to a development of (at first) non-convergent sub-cultures that will inhabit the web alone and will have only loose (or even superficial) connections to the original culture itself and to the language-based system they utilise on the web. Now, that’s a revolutionary idea – not a transformation of existent cultures, but their mutation into new cultures. The next question is – following convergence of communications, will there be a convergence of atomistic new web-based cultures? Will the web lead to the emergence of a truly global, non-localized culture? And here is another ‘futuristic’ idea for you that comes off the same core – once convergence of technologies and communications takes place, the next step will be to merge these with biological systems. Then, new cultures – until then existent solely in the virtual world – will become physical – or biological. What happens next? Imagine your children’s computer games acted out in real physical universe? May be not by 2030… but what about by 2050?]


Number 3:

“There is a strange paradox at the heart of human nature. We humans are the most sociable creatures on earth, with a remarkable ability to cooperate with one another. … Human beings are also creatures of unparalleled ferocity. No other animal is capable of the horrors--the wars, genocides, torture and oppression--that we have regularly visited upon our fellow human beings. This is all the more perplexing because killing does not come easily to us. …What goes on in the human mind to make… brutality possible? We dehumanize our fellow human beings when we convince ourselves …that they are less than human... The immense destructive power of dehumanization lies in the fact that it excludes its victims from the universe of moral obligation, so killing them is of no greater consequence swatting a mosquito, or poisoning a rat. If dehumanization is a key factor in war and genocide, we ought to be working very hard to prevent it.”

[This is more like a real 21st century challenge, although the humanitarian dream has been with us for a very, very long time. One interesting aspect of the entire idea of finding a ‘cure’ for cruelty and inhumanity is that all, even theoretical, ones seem to lead to a mind control and totalitarian suppression of thought in general. And the article on the topic linked above leaves absolutely no clues as to how we can resolve the truly horrific problem of dehumanization without actually dehumanizing ourselves in the process.]

Economics 19/06/2010: A quote

An unexpected quote (hat tip to Open Europe):

"What went wrong wasn't what happened this year. What went wrong was what happened in the first 11 years of the euro's history. In some ways we were victims of our success...It was like some kind of sleeping pill, some kind of drug. We weren't aware of the underlying problems".

European Council President Herman Van Rompuy, 14 June 2010

Perhaps the only thing worth disagreeing here with is the idea that 'we weren't aware':

1. 'I didn't know' is not a legitimate defense for sleeping on the job.
2. Why weren't they listening?
3. Will anyone bear the consequences?
   

Economics 18/06/2010: Banks, bonds and banks again

Brian Lenihan confirmed yesterday that the Government is now seeking an extension of the bank guarantee scheme by 3 months to the end of 2010 to coincide with capital requirement deadline set by the FR. The extension with cover new liabilities of 3mo-5 years and will not cover subordinated debt. This was expected, given the profile of maturing banks debt and the dire conditions in the funding markets where investors have been reluctant to extend new funds to Irish banks (based on the high risk perception concerning the sector and geography) and the interbank lending markets remain in elevated yields territory. Sovereign spreads reaching 313 bps for 10 year paper over the bund are not helping either, record levels, indeed.

Added uncertainty weighted on the banks is stemming from the rumors surrounding the issue of regulatory controls that the Central Bank is expected to impose on banks loans distribution across various sectors. It is expected that the CB will push (next week?) for specific maximum exposure ceilings on lending to property sector for banks. If so, this will require serious re-thinking of Irish banks models away from the traditional reliance on property-based collateral deals going to finance more property-related investments and in favour of more business and consumer oriented banking.

The winner - of the Big 4 - here will be BofI, which has a much more customer-oriented model of consumer banking than AIB (not to mention ptsb or Anglo). But all banks will find it challenging to bring in more consumer orientation in the environment where thy are trying to push up margins on existent paying clients. And even more importantly, all banks will find it difficult to enter serious business investment markets.

Meanwhile, on wholesale funding side, things are now so desperate that the EU - never the first to push for greater transparency - is being forced to publish the results of stress tests on the region’s banks. Expected before the end of this month, the tests are likely to be a hogwash - Merkel already stated that the 'EU has taken precautionary measures' in relation to stress tests results. Whatever this might mean, one wonders.

There's an excellent post on econbrowser blog (here) on the extent of the PIIGS banks problems and the expected size and geographic distribution of potential contagion. A chart below says it all:
I mean, really, folks, we beat Greece and Portugal as a combination. And for UK banks, we beat all other 3 sickest puppies.

Economics 16/10/2010: Organizational systems and uncertainty

I came across this very interesting, and to me - far reaching - paper on the effects of organizational structures on the organization's ability to cope with uncertainty and change. Karynne L. Turner, Mona V. Makhija. “Measuring what you know: an individual information processing perspective” (April 15, 2010). Atlanta Competitive Advantage Conference 2010 Paper (here).

According to the information processing perspective, the organization’s ability to draw upon and utilize information is dependent on the relationship between structure and the ability of individuals to process information, facilitated by specific organizational aspects of the firm. The study considers the effect of two types of structure, organic (integrated or systemic) and mechanistic (siloed), on individuals’ ability to gather, interpret and synthesize information, and their problem-solving orientation. Evidence shows that individuals develop more information processing capability under organic than mechanistic structures, which in turn creates more problem solving orientation in individuals.

In short, the study lends support to the premise that better integrated, more diversified across skills and less siloed organizations produce more effective and efficient gathering, processing and interpreting of information, as well as better problem solving.


Effective management of knowledge is the basis of firms’ ability to compete (Zander and Kogut, 1995; Nonaka, 1994). This is achieved through organizational design (Teece at al., 1997) that underlies “the means by which firms acquire, disseminate, interpret and integrate organizational knowledge”.

Organizational structure embodies a number of key elements, such as control and coordination or management mechanisms, and human capital management that allocate tasks to work units and individuals, and coordinate them in a way that achieves organizational goals. The manner in which this is done is critical due to problems created by

• External uncertainty associated with suppliers, competitors and consumer demand (Gresov and Drazin, 1997; Sine, Mitsuhashi and Kirsch, 2006), or
• Internal uncertainty, due to the complexity of internal coordination, measurement difficulties and changing processes (Habib and Victor, 1991).
  

Uncertainty reduces the effectiveness of pre-established routines, technologies or goals, and increases the importance of problem solving (Becker and Baloff, 1969)). The more work related uncertainty increases, the greater the need there will be for information processing (Turner and Makhija, 2006 and Tushman, 1979).

One way in which an organization addresses uncertainty is by assigning specific responsibilities to specialized subunits, which collect, process and distribute information acting as “a set of nested systems” (Daft and Weick, 1984).

Literature distinguishes two types of organizational structures, mechanistic and organic. These structures differ in the distribution of tasks, the flow of information among individuals and across units, and the extent to which there is interaction with the environment (Shremata, 2000; Gibson and Birkinshaw, 2004).

Mechanistic forms of organization are characterized by hierarchical division of labor, in which communication tends to be in one direction – top to bottom. Individuals develop deep expertise in their own designated jobs, which tend to be clearly specified and specialized in individual knowledge. The mechanistic structures do not allow for much flexibility (Parthasarthy and Sethi, 1993).

Organic forms of organizations are based on horizontally-administered teams, in which all members participate in management decisions (Baum and Wally, 2003), allowing for worker autonomy, responsibilities adaptation. Team members developing competence across multiple tasks, thus diversifying their skills and knowledge sets. Individuals have broader unit-level knowledge rather than just one job and develop greater flexibility.

The structural differences between mechanistic and organic organizational forms are likely to influence the development of information processing capability in organizational members, reflected in organization’s ability to gather, interpret and synthesize information. Turner and Makhija (2010) consider the impact of different types of structures on each of these three aspects of organizational members’ information processing capability.

Turner and Makhija (2010) postulate a set of testable hypotheses all of which are confirmed:

H1: Organic structures lead to more gathering of information than mechanistic structures.
Implication: uncertainty is reduced in organic (integrated or more horizontal) structures through reduced information asymmetries vis-à-vis external environment.

H2: Organic structures lead to more similarly interpreted information than mechanistic structures.
Implication: information asymmetries are reduced across the broader range of the organization structures in the organic setting.

H3: Organic structures lead to more synthesized information than mechanistic structures.
Implication: organic systems are better capable of integrating information of various types.

H4: More gathering of information is associated with greater problem solving orientation.
Implication: organic systems are better able to cope with converting uncertainty into manageable risks systems.

H5: More similarly interpreted information is associated with greater problem solving orientation.
Implication: better information processing in organic systems results in better problem solving, so information is used more effectively.

H6: More synthesized knowledge is associated with greater problem solving orientation.
Implication: individuals also tended to synthesize, or understand the interrelationships among different types of information, much better than individuals working in mechanistic structures.

H7: Information processing capability mediates the relationship between organizational design and problem solving orientation
Implication: the effects of individuals’ information processing on their problem solving orientation is greater in the organic structures, reflecting their comfort with problem situations in their work.

Turner and Makhija (2010) research shows that, when operating in two different types of structures, individuals process information differently in all three respects: gathering, interpreting, and synthesizing information.

These findings have several far-reaching implications for the organizational structures found in Ireland.

Firstly, it is clear that hierarchical and fixed systems approach to public services provision – characterized by the lack of communications between vertically-integrated public sector departments and organizations leads to their inherently lower ability to absorb, process and implement informational processes that manage uncertainty.

Secondly, this shows why successful entrepreneurial ventures are horizontal in nature and less siloed.

Third, it shows that our political system – with disproportionate powers allocated to the executive, as opposed to more uniform distribution of powers between the executive, legislative and judiciary – is similarly to the public sector less equipped to handle uncertainty.

Economics 15/06/2010: Negative equity 3

Here is the third and last post in the series on negative equity based on my TCD speech (see here).

Rising negative equity has implications for financial stability:

Domestic mortgage lending by the major banks represents over x5 times their core Tier 1 capital in the UK and roughly 10 times in Ireland. Even post disposal of its assets (assuming rosy valuations), AIB’s multiple will be over x11 of its risk-weighted assets. BofI – x7-8. And these are the better ones of the Irish banking lot. In addition, around 40% of all outstanding UK mortgage debt has been used to back securities.

Large losses on these mortgage loans and associated securities can erode banks’ capital positions, affecting both lenders’ willingness and ability to lend and, in extreme cases, their solvency.

Both of the above effects can have implications for aggregate demand and the supply capacity of the economy, highlighting the interdependency of financial stability and monetary policy. Again, in the case of Ireland, the two effects are reinforced by the large exposure of the Exchequer to banks balancesheets and to the property markets.

The defining feature of the materialised losses, and their associated economic effects, is the value of debt at risk (loss given default) and the coincidence of that with the probability of default.

Rising negative equity has implications for loans default probabilities:

In economic literature, negative equity is a necessary condition for default to occur since borrowers with positive equity can sell their house and use part of the proceeds to pay off their mortgage. Transaction costs (high in Ireland) and transaction lags (also extremely long in Ireland) act to further increase this effect. For example, a household with positive equity of ca 10% will still trigger a partial default on the mortgage if it takes a year to close the sale (8% funding opportunity cost per annum) and if closing costs add up to 2% of the sale price.

However, negative equity is not a sufficient condition for default to occur, as discussed in “Negative Equity and Foreclosure: Theory and Evidence” by C. Foote, K. Gerardi and P. Willen (June 05, 2008, FRB Boston Policy Discussion Paper No 08-03). Similarly, in the UK, May and Tudela (2005) find no evidence that negative equity increased the likelihood of a household experiencing mortgage payments problems between 1994 and 2002, although their sample does extend over a lengthy period of robust economic growth and rising incomes. The latter two aspects of the sample are not present in today’s Ireland.

But, as Heldebrandt, Kawar and Waldron (2009) highlight, “if a household is experiencing difficulties meeting their mortgage payments, negative equity can increase the probability of default by reducing the household’s ability to make payments by preventing equity withdrawals.” Benito (2007) found that households are more likely to withdraw equity from their homes if they have experienced a financial shock. Negative equity can affect a household’s ability to do that because of credit constraints.

Furthermore, negative equity can increase the probability of default by reducing household’s willingness to make mortgage payments, since defaulting can reduce the debt burden of the household. In Ireland, despite our anachronistic bankruptcy laws, this option is still available for anyone willing to emigrate. You might as well call this www.book-your-one-way-ticket.ie effect, as households leaving Ireland fleeing bankruptcy will have:

1. a very strong incentive to emigrate; and
2. a very strong incentive never to return for the fear of debt jail.

Negative equity may significantly increase the probability of default of buy-to-let mortgages over and above that of owner-occupiers as costs of defaulting on a buy-to-let mortgage may be lower because defaulting does not lead to loss of residence. In addition, buy-to-let mortgages are, at least in some cases, registered via businesses, implying no recourse on family homes and wealth.

Overall, available economic evidence does suggest that negative equity plays a significant role in mortgage defaults:

• Coles (1992) presents results from a 1991 survey of lenders in which a high LTV ratio was frequently noted as an important characteristic of borrowers falling behind in meeting their mortgage payments.
• Brookes, Dicks & Pradhan (1994) and Whitley, Windram & Cox (2004) find that a reduction in the aggregate housing equity in the UK was associated with an increase in arrears.

Overall, Heldebrandt, Kawar and Waldron (2009) conclude that “evidence suggests that the level of household defaults, and the impact of negative equity on financial stability, is likely to depend on conditions in the broader macroeconomic environment”. And Ireland is at a clear disadvantage since the combined macroeconomic shocks (decline in GDP/GNP, rising unemployment and contraction in private sector credit) are much more severe here.

Rising negative equity has implications for the size of the expected banks losses:

When bank borrowers face negative equity, as probability of default and the value-at-risk in default rise, banks have an incentive to stave off the actual mortgage default. To do this, banks engage in:

• Renegotiations of covenants (loans extension, provision of a grace period, interest only repayments etc)
• In extreme cases – joint equity ownership in asset (though banks will usually engage in this type of transactions under regulatory duress)
  

All of these measures aim to put the borrower into a position to eventually repay the loan in full.

However, in cases where default in unavoidable, the loss to be realised by the bank on any given loan depends on the recovery that can be achieved if the borrower defaults. Negative equity, or positive equity that does not exceed the sum of the cost of carrying the loan during the sale, plus the cost of sale, will imply a net loss on the default. From the bank point of view, the problem is not in the actual level of individual defaults, but in the combined level (aggregate) of negative equity net of costs and recovery values.

Such net losses impact not only the actual mortgage book, but also securitised pools that can be held off balance sheet, as current negative equity puts at risk future revenue against which the book is securitised. The end result on mortgage backed securities side is to reduce the value of MBS asset and, as Heldebrandt, Kawar and Waldron (2009) point out this can induce a second order effect of changing risk perceptions and investors’ sentiment “regardless of the actual performance of any given portfolio of loans”.

Both types of losses lead the banks to record write downs on their mortgage books and securities held. If these are large enough, banks’ capital ratios will be reduced.

In the case of Ireland the problem is compounded as the banks are actively delaying recognition of losses on negative equity. These delays mean that banks are likely to pay elevated costs of external funding over longer period of time. In addition, these delays lead to losses compression – the situation where banks recognize significantly larger volumes of impaired assets later in the crisis cycle. Bunching together losses creates a much more dramatic investors’ loss of confidence in the bank.

In addition, negative equity-driven impairments, plus delayed recognition of such impairments lead to suboptimally high demand for capital from the banks. If this coincides with the period of severe credit crunch, monetary policy aimed at increasing economy-wide liquidity flows can become ineffective, as banks park added liquidity on their balance sheets, creating a liquidity trap. This is evident throughout the crisis, but by all possible monetary policy metrics, it is much more prevalent in Ireland, where even today credit available to the private sector continues to contract. Irish banks are hoarding liquidity and are raising lending margins to offset expected, but undisclosed writedowns. This problem is compounded by Nama which induces greater uncertainty onto banks balance sheets through its hardly transparent or timely operations.

Negative equity and generational asset gap:

In Ireland, the problem of negative equity is further compounded by the generational spread of negative equity to predominantly younger, more productive and more mobile (absent negative equity) households. These households today face higher probability of unemployment (thanks to our unions-instituted and supported ‘last in – first out’ labour market policies). They also much deeper extent of the negative equity because of higher cost of financing their original mortgages and entering the housing market.

The generational effects of negative equity are compounded by geographic distribution of the phenomena – with younger households being more likely to reside in the areas of excess supply of new housing, with poor access to alternate jobs, should they experience unemployment.

Finally, it is the younger households that are subject to twin effects of higher probability (and deeper extent) of negative equity and depleted savings (due to high cost of entry into the housing market). This implies that it is the very same households which have the greatest incentive to engage in precautionary savings motive.


So traditionally, economies grow by:

• encouraging the young to acquire new assets (invest and save); and
• encouraging the old to consume (divest out of savings).

With negative equity, Nama and pressured banks margins, Ireland is:

• forcing the better (more productive today and in the future) young to emigrate;
• keeping the remaining young deep in the negative equity (neither capable of investing in the future, nor of moving to find a lost job today);
• underwriting - at the expense of younger, tax paying generations - continued excessive provision of pensions to retired public sector workers;
  
• forcing younger families to cut deeper and deeper into their children education budgets and own training and education funds in order to assure they continue paying on the asset that will never have net positive return on investment; and
• incentivising the old to remain in their highly priced (if only rapidly losing value) homes backed by slacked consumption due to inability to monetize their pensions savings.

In what economics book is this scenario better than any moral hazard problem that can be incurred in the short run by reforming our bankruptcy system to an American-styled 'restart' button?

Economics 15/06/2010: Negative equity 2

This is the second post of three consecutive posts on the effects of negative equity in Ireland.

Negative equity can lead to a reduction in consumer spending, collateral & credit

This can take place via four main pathways:

1. Housing equity can be used as collateral to obtain a secured loan on more favourable terms than a loan which is unsecured. This channel for lower cost financing is cancelled out by the negative equity.
2. Falling collateral values may also affect the cost of servicing existing mortgages if borrowers have to refinance at higher interest rates when their existing deals expire (eg when exiting temporarily fixed-rate or tracker mortgages). That would reduce income available for consumption, which may further reduce demand.
3. Households on adjustable rate mortgages are facing additional pressure of higher banks margins. Since vintages of many ARMs are coincident with 2005-2007 period, negative equity has direct and significant impact on them. Nama exacerbates this impact by forcing banks to up their margins on performing loans, pushing more and more households into not just negative equity, but virtual insolvency.
4. Fourth, falling values of housing equity also reduce the resources that homeowners have available to draw on to sustain their spending in the event of an unexpected loss of income (eg due to redundancy, illness or a birth of a child). By reducing the value of housing equity, falling house prices may lead some homeowners to seek to rebuild their balances of precautionary saving at the expense of consumer spending and investment.
   

Note that precautionary savings are held in highly liquid demand deposits – a fact that I will use below. In general, households with high amounts of housing equity may not respond much to falling house prices, because their demand for precautionary savings balances may already be satisfied through their positive net worth balances on the house. Households with low or negative equity have an asymmetrically stronger incentive to save in a form of short-term deposits.

Rising negative equity can also result in a reduced supply of credit to the economy as a whole:

Negative equity can raise the loss that lenders would incur in the event of default (loss given default) and the probability of a loss. That can make banks less willing or able to supply credit to households and firms.

Per Benford and Nier (2007) Basel II regulations, which require banks to hold more capital against existing loans when their anticipated loss given default rises, can reinforce that.

If credit is more costly or difficult to obtain, households and firms are likely to borrow less, leading to lower demand through lower consumer spending and investment. This, in turn, can lead to reduced business investment.

Expectation hypothesis suggests that negative equity effects on willingness to borrow and lend can extend beyond those immediately impacted as other households anticipate their own asset value decline toward negative equity.

Blanchflower and Oswald (1998) paper showed that a reduction in credit availability may also have some effect on the supply capacity of the economy by reducing working capital for smaller businesses and the capital available for small business start-ups. In addition, a recent (June 2009) paper “Reduced entrepreneurship: Household wealth and entrepreneurship: is there a link?” by Silvia Magri, Banca d’Italia, published by the Bank of Italy (Working paper Number 719 - June 2009) shows that negative house equity can result in reduced entrepreneurship, as many new businesses are launched on the back of borrowing secured against primary residencies or other real estate assets.

Rising negative equity can also result in a reduced household mobility:

Negative equity can affect household mobility by discouraging or restricting households from moving house. Two fathers of behavioural economics, Tversky and Kahneman (1991) argued that households may be reluctant to move because they would not wish to realise a loss on their house. Notice, that our so-called ‘smart’ politicians often claim that negative equity is never a problem unless someone wants to move. Actually, it is a problem even if someone does not want to move, but has to move because of their changed employment or family circumstances.

Tatch (2009) shows that a household in negative equity would be unable to move if they were unable to repay their existing mortgage and meet any down payment requirements for a new mortgage on a different house. This is even more pronounced in Ireland due to the nature of Irish bankruptcy laws.

Hanley (1998) shows that the effect of negative equity on mobility were quantitatively significant during the early 1990s in the UK. The paper estimates that of those in negative equity in the early 1990s, twice as many would have moved had they not been in negative equity. The paper argues that reduced household mobility leads to a reduction in the supply capacity of the economy by increasing structural unemployment and reducing productivity.

Reduced household mobility implies a reduction in the number of households moving home. This can have adverse implications for tax receipts, spending on housing market services and certain types of durable goods as highlighted in Benito and Wood (2005). So as negative equity increases, tax revenues and economic activity in the housing sector and associated white goods sectors falls.
