The paper discusses the currents that led to the 2007-2009 financial crisis. We discuss the crisis in a historical context and present evidence regarding the incidence and unit price of risk. Our results show that the unit price of risk prior to the subprime crisis is comparable to the price of risk prior to the great depression and similar to the price of risk at onset of the technology bubble. We then discuss global imbalances, the associated risks with regard to international optimal allocation of capital, and arrangements to minimize problems of global imbalances.

We estimate default measures for US banks using a model capable of handling volatility clustering like those observed during the Global Financial Crisis (GFC). In order to account for the time variation in volatility, we adapted a GARCH option pricing model which extends the seminal structural approach of default by Merton (J Finance 29(2):449, 1974) and calculated "distance to default" indicators that respond to heightened market developments.With its richer volatility dynamics, our results better reflect higher expected default probabilities precipitated by the GFC. The diagnostics show that the model generally outperforms standard models of default and offers relatively good indicators in assessing bank failures.

This paper revisits the controversy over whether retail gasoline prices respond to increases in upstream prices more rapidly than decreases. Using threshold and momentum models of cointegration and daily data at different stages in the distribution chain, we find that transmission between upstream and downstream prices is mostly asymmetric in the momentum model: increases in upstream prices are passed on to downstream prices more quickly than decreases. We distinguish between small and large shocks and show that the asymmetry is more pronounced for small shocks, which may be due to consumer search costs.

This paper investigates episodes of financial stress and its relationship to economic activity in some Southeast Asian economies. To that end, we use a dynamic factor model to construct a financial stress index for Indonesia, South Korea, Malaysia, the Philippines, and Thailand and examine the relationship between financial stress and economic activity. Our financial stress index consists of riskiness in the banking sector, security market risk, currency risk, external debt and sovereign risk. Empirical results indicate that our financial stress index tracks recessions closely in the sample and impulse response functions suggest financial stress causes significant economic slowdowns.

Conventional models of economic behavior have failed to account for a number of observed empirical regularities in macroeconomics and international economics. This may be due to preference specifications in conventional models. In this paper, we consider preferences with the "spirit of capitalism" (the desire to accumulate wealth as a way of acquiring status). We analyze a number of potential effects of international catching-up and the spirit of capitalism on savings, growth, portfolio allocation and asset pricing. Moreover, we obtain a multi-factor Capital Asset Pricing Model (CAPM). Our results show that status concerns have non-trivial effects on savings, growth, portfolio allocation, asset prices and the foreign exchange risk premium.

There is a large and growing literature on the welfare cost of inflation. However, work in this area tend to find moderate estimates of welfare gains. In this paper we reexamine welfare costs of inflation within a stochastic general equilibrium balanced growth model paying a particular attention to recursive utility, portfolio balance effects, and monetary volatility and monetary policy uncertainty. Our numerical analysis shows that a monetary policy that brings down inflation to the optimum level can have substantial welfare effects. Portfolio adjustment effects seem to be the dominant factor behind the welfare gains.
