Choice of Mortgage Contracts: Evidence from the Survey of Consumer Finances

This study revisits the empirical question of the determinants of the choice between fixed- and adjustable-rate mortgages using data from the Survey of Consumer Finances that overcome some of the data limitations in previous studies. The results from a logit model of mortgage choice indicate that pricing variables and affordability are important considerations. We also find that factors, such as mobility expectations, income volatility and attitudes toward financial risk largely influence mortgage choice, with more risk-averse borrowers preferring fixed-rate mortgages. For households that are less risk averse, the mortgage type choice decision is less sensitive to pricing variables and income volatility, and affordability factors are not significant. These findings provide empirical support that underscores the importance of attitudes toward risks in mortgage choice. Copyright (c) 2009 American Real Estate and Urban Economics Association.

Do Homeowners Increase Consumption after the Last Mortgage Payment: An Alternative Test of the Permanent Income Hypothesis

The maturity date of a mortgage loan marks the end of monthly mortgage payments for homeowners. In the period after the last payment, homeowners experience an increase in their disposable income. Our study interprets this event as an anticipated increase in income, and tests whether households smooth consumption over the transition period as predicted by the rational-expectation life-cyclepermanent-income hypothesis. We find households do not alter nondurable-goods consumption in the period following the last mortgage payment. Instead, they increase both financial savings and savings in durable goods such as house furnishings and entertainment equipment in the year of the last mortgage payment.

Financial frictions, trade credit, and the 2008–09 global financial crisis

This paper studies the role of the credit crunch in the severe contraction of trade and economic activity at the height of the 2008-09 global financial crisis, using firm-level data from six emerging market economies in Asia. We construct firm-specific measures of global demand, which allow us to disentangle the effect of falling demand from that of financial constraints on sales. The results indicate that: (1) Although the fall in demand adversely affected the sales of all firms during the crisis, sales declined by less for firms with better pre-crisis financial conditions. (2) In the face of the decline in external financing opportunities, some firms relied more on trade credit from suppliers to supplement operating capital during the crisis, which allowed them to post relatively better sales. (3) Export-intensive firms with comparable financial vulnerability resorted less to trade credit as an alternative source of finance, and hence experienced sharper declines in sales than the domestically-oriented firms. These findings point to the presence of credit frictions among the factors that contributed to the disproportionately large decline in international trade during the crisis.This paper studies the role of the credit crunch in the severe contraction of trade and economic activity at the height of the 2008-09 global financial crisis, using firm-level data from six emerging market economies in Asia.

International financial spillovers to emerging market economies: How important are economic fundamentals?

We assess the importance of economic fundamentals in the transmission of international shocks to financial markets in various emerging market economies (EMEs). Our analysis covers the so-called taper-tantrum episode of 2013 and six earlier episodes of severe EME-wide financial stress since the mid-1990s. Cross-country regressions lead us to the following results: (1) EMEs with relatively better economic fundamentals suffered less deterioration in financial markets during the 2013 taper-tantrum episode. (2) Differentiation among EMEs set in quite early and persisted throughout this episode. (3) Controlling for economic fundamentals, we also find that, during the taper tantrum, financial conditions deteriorated more in those EMEs that had earlier experienced larger private capital inflows and greater exchange rate appreciation. (4) For earlier episodes, we find little evidence of investor differentiation across EMEs being explained by differences in their relative vulnerabilities during EME crises of the 1990s and early 2000s. (5) That said, differentiation across EMEs based on fundamentals does not appear to be unique to the 2013 episode. Differences in economic fundamentals played a role in explaining the heterogeneous EME financial market responses during the global financial crisis of 2008, and the role of fundamentals appeared to progressively increase through the European crisis in 2011 and subsequently the 2013 taper tantrum.

Effects of Financial Autarky and Integration: The Case of the South Africa Embargo

The economic embargo imposed on South Africa between 1985 and 1993 brought the country closer to financial isolation. This paper interprets the imposition and removal of the embargo as financial autarky and financial integration ‘natural experiments’, and studies the effects on the economy. The aggregate data indicate a decrease in the levels and growth rates of investment, capital, and output during the embargo period relative to the pre-embargo and post-embargo periods. To further rationalize the findings in the aggregate data, we calibrate a neoclassical growth model to the South African economy. During the transition to steady-state, we model the embargo by limiting the country’s ability to borrow for a period corresponding to the duration of the embargo. The derived dynamics for investment, capital, and output support the view of a positive (negative) link between financial integration (isolation) and economic growth.

The Asian Financial Crisis, Uphill Flow of Capital, and Global Imbalances: Evidence from a Micro Study

This study assesses the role of the Asian financial crisis of the late 1990s in the emergence and persistence of the large current account surpluses across non-China emerging Asia, which have been a significant counterpart to the U.S. current account deficit. Using panel data encompassing nearly 3,750 firms, we trace the current account surpluses to a marked and broad-based decline in corporate expenditures on fixed investment in the aftermath of the crisis that cuts across a wide spectrum of countries, industries, and firms. The lower corporate spending in turn depressed aggregate investment rates, widened the saving-investment gap, and allowed the region to turn into a net exporter of capital. We then consider the factors behind this reduction in postcrisis corporate investment. While weaker firm-level fundamentals in the postcrisis period seem to explain part of the drop in investment rates, ongoing re-structuring owing to large debts accumulated and excess investment undertaken in the run-up to the crisis has been the main source of restraint postcrisis corporate investment. The results suggest that even after a decade, the effect of the financial crisis is still affecting corporate investment decisions in emerging Asia, and that as the restructuring completes its course, investment rates will likely rise to contribute to a gradual reduction in the regions current account surpluses.

South Africa's Post-Apartheid Two-Step: Social Demands versus Macro Stability

During Apartheid, there was little need for redistributional policies or to borrow for public works since the vast majority of the population was underserved. With the arrival of a representative democracy in 1994, however, South Africa faced a unique problem--providing new and improved public services for the majority of its citizens while at the same time ensuring that filling this void would not undermine macroeconomic stability. Over the past fifteen years, policy makers have achieved macrostability, but progress on social needs has been below expectations and South Africa continues to lag behind its peers. This paper reviews the progress made so far and examines the challenges ahead for the upcoming administration. Our analysis suggest an increase in skill formation as a possible solution to the policy dilemma of fulfilling the outsized social demands while maintaining macrostability.

Estimating the Long-Run User Cost Elasticity for a Small Open Economy: Evidence Using Data from South Africa

This paper estimates the long run elasticity of the demand for fixed nonresidential capital (both equipment and structures) to changes in its user cost using a quarterly panel of two-digit manufacturing data from South Africa from 1970 to 2001. Using a difference specification that does not rely on cointegration, we find highly significant estimates of the user cost elasticity on the order of -0.80. These estimates contrast sharply with many previous studies that obtained small and/or statistically insignificant estimates of the user cost elasticity using U.S. data. This discrepancy may owe to the possibility that the capital demand curve is better identified in a small open economy because shocks to capital supply are more likely to be exogenous. The economic embargo imposed on South Africa from 1985 to 1993 forced its economy to become more closed and therefore provides a unique natural experiment to assess this conjecture. Estimates of the user cost elasticity over this period are small and statistically insignificant, similar to the findings of previous studies where the user cost was likely endogenous. These findings underscore the importance of identification in estimating the user cost elasticity of capital demand.

The "Elusive" Capital-User Cost Elasticity Revisited

This paper sheds new light on the estimation of the long-run elasticity of the demand for business capital---for a measure of capital that includes both equipment and structures---to changes in its user cost using a quarterly panel of two-digit manufacturing industries from South Africa from 1970 to 2000. Highly significant estimates of the user cost elasticity that are in the vicinity of the -1.0 benchmark implied by a Cobb-Douglas production function are obtained using a variety of specifications, including panel cointegration techniques that correct for small sample bias. Unlike most previous studies, meaningful elasticity estimates are also obtained using stationary panel specifications. The robustness of these estimates may be due, in part, to the possibility that the capital demand curve is better identified in a small open economy where shocks to capital supply are more likely to be exogenous. The economic embargo imposed on South Africa from 1985 to early 1994 temporarily forced its economy to become more closed and therefore provides a unique opportunity to assess the importance of identification in the estimation of the user cost elasticity. User cost elasticity estimates using embargo and non-embargo period data are consistent with a substantial bias from endogeneity.

Emerging Market Capital Flows and U.S. Monetary Policy

Accordingly, in this note we analyze the drivers of EME capital flows, focusing in particular on the role of U.S. monetary policy and other potential factors in the decline in capital flows to EMEs since 2010.
