What motivates a subprime borrower to default?

This paper uses a real options approach to analyse the exercise of the default option embedded in mortgages. In particular, it examines a subprime household who borrows at a premium, but hopes to refinance at prime rates if their house appreciates. We show how these optimal default decisions can be used to calculate probabilities of default – an important input for risk management and pricing purposes. Numerical examples are provided, calibrated to US data. In a low interest rate environment, the credit-upgrade potential may discourage subprime borrowers from defaulting. However, default probabilities are highly sensitive to changes in interest rates and house prices. This provides a rational explanation for the prevalence of adjustable rate mortgages among subprime borrowers, and the subsequent large numbers of defaults, when interest rates rose and house prices declined.     

China's regional income disparityAn alternative way to think of the sources and causes1

Using data on China's provincial economies for the period 1978–2005, we decomposed the causes and factors that have contributed to inter‐regional per capita income disparity. Variance in capital per employee and variance in capital elasticity are found to be the two main sources of income disparity while the employment–labour force ratio is shown to be an important factor in containing the rise of income disparity. An analysis on inter‐regional factor reallocation effects reveals their relatively small and insignificant contributions to overall growth performance. It is also discovered that capital has in most years flowed in the right direction to pursue higher marginal productivity across provincial economies. Inter‐provincial labour movement, on the other hand, had not displayed significant equilibrating effects until institutional reforms started to allow freer inter‐regional labour mobility in later years. Generally, we conclude that market‐oriented factor mobility has played a crucial role in equalizing factor returns as well as enhancing growth efficiency across regions.     

REVISITING INFORMAL EMPLOYMENT AND SEGMENTATION IN THE SOUTH AFRICAN LABOUR MARKET

This study revisits the definition of informal employment, and it investigates the puzzle of high open unemployment co‐existing with relatively limited informal employment in South Africa. We estimate earnings equations using data from the September 2004 Labour Force Survey and present evidence of persistent earnings differentials not only between formal and informal employment, but also between types of informal employment. These persistent earnings differentials are suggestive of complex segmentation in the South African labour market and challenge the presentation of informal employment as an undifferentiated residual with no barriers to entry or mobility.     

Intraday return and volatility relationships between the Ibex 35 spot and futures markets

This paper analyses the intraday lead-lag relationships between returns and volatilities in the Ibex 35 spot and futures markets. Using hourly data, we jointly analyze the interactions between markets, estimating a bivariate error correction model with GARCH perturbations which captures stochastically the presence of an intraday U-shaped curve for both spot and futures market volatility. Our findings show a bidirectional causal relationship between market volatilities, with a positive feedback. This two-way transmission of volatility is consistent with market prices evolving according to a long-run equilibrium relationship, and shocks affecting both markets in the same direction. Our empirical results also support a unidirectional cross interaction from futures to spot market returns. This pattern suggests that the futures market leads the spot market in order to incorporate the arrival of new information.     

Beyond Flying Geese: The Expansion of East Asia's Electronics Trade

The flying geese (FG) hypothesis, which asserts the sequential catching‐up processes of the latecomers, holds well in the past. Yet a simultaneous boom within the electronics industry across East Asia casts doubt on the applicability of the hypothesis. By using the RCA and NET indices, the paper finds that the FG pattern shows in the electronics industry as a whole, but not always so at the disaggregated level. This suggests that the FG formation may not appear in other industries, if they are involved in international production fragmentation or have differentiated products, and if certain latecomers have become new leaders.     

Are Expected Inflation Rates and Expected Real Rates Negatively Correlated? A Long‐Run Test of the Mundell‐Tobin Hypothesis

Some empirical evidence suggests that the expected real interest and expected inflation rates are negatively correlated. This hypothesis of negative correlation is sometimes known as the Mundell‐Tobin hypothesis. In this article we reinvestigate this negative relation from a long‐term point of view using cointegration analysis. The data on the historical interest rate on T‐bills and the inflation rate indicate that the Mundell‐Tobin hypothesis does not hold in the long run for the United States, the United Kingdom, and Canada. We also obtain similar results using the real interest rate on index‐linked gilt traded in the United Kingdom.     

The term structure of real interest rates: theory and evidence from UK index-linked bonds

This paper studies the behavior of the default-risk-free real term structure and term premia in two general equilibrium endowment economies with complete markets but without money. In the first economy there are no frictions as in Lucas (Econometrica 46 (1978) 1429) and in the second risk-sharing is limited by the risk of default as in Alvarez and Jermann (Econometrica 68 (2000) 775; Rev. Financial Studies 14 (2001) 1117). Both models are solved numerically, calibrated to UK aggregate and household data, and the predictions are compared to data on real interest rates constructed from the UK index-linked data. While both models produce time-varying risk or term premia, only the model with limited risk-sharing can generate enough variation in the term premia to account for the rejections of expectations hypothesis.     

Valuing the Option to Purchase an Asset at a Proportional Discount

I analyze the value of a nonstandard call option that allows the holder to purchase an underlying asset at a discount proportional to the asset's market price. Several applications for this type of option exist, including its use in employee compensation contracts. I derive the value of this option for a dividend-paying asset and for an option whose exercise price reflects a time-varying discount factor. The derived value incorporates the optimal time at which the option should be exercised. One application of this option relates to a residential real estate program in China.     

Indonesian Local Government Spending,Taxing and Saving: An Explanation of Pre‐ and Post‐decentralization Fiscal Outcomes*

As a result of Indonesia's decentralization program, local governments have gained significantly more responsibility for service delivery, considerably larger fiscal resources, and much greater authority over the use of those resources than before. The present paper develops a simple budget model to describe and explain the substantial differences in pre‐ and post‐decentralization local government fiscal behavior related to spending, taxing and saving. During the post‐decentralization period special attention is paid to the fiscal behavior of natural resource rich regions. Among other things, the evidence suggests that: post‐decentralization local government spending is partly responsive to increasing needs and partly the subject of elite capture; local government taxation has become more aggressive under decentralization and appears to be mostly driven by local bureaucratic expectations related to routine overhead budgets; and the increased savings of local governments during the post‐decentralization period is determined to a large degree by delayed central government transfer payments.
