The paper presents a model of irreversible investment under uncertainty, where investment takes place whenever a threshold level of marginal returns is reached. The threshold depends positively on price volatility; a change from high to low inflation induces an upward capital stock adjustment. In economies that move in and out of temporary stabilizations, the observed effect is a negative inflation-investment correlation that replicates previous empirical findings, due to purely short-term dynamics. I study how this correlation is affected by the expected duration of each regime. Empirical evidence from ten inflationary economies confirms the predictions of the model.
This semiannual report examines the short and medium-term challenges for Latin America and the Caribbean (LAC) as the external factors that were instrumental in the region s recent performance recede. In particular, we address the role of the exchange rate as a counter-cyclical policy tool to buffer adverse external shocks.
This paper examines how public disclosure of banks’ risk exposure affects banks’ risk-taking incentives and assesses how the presence of informed depositors influences the soundness of the banking system. It finds that, when banks have complete control over the volatility of their loan portfolios, public disclosure reduces the probability of banking crises. However, when banks do not control their risk exposure, the presence of informed depositors may increase the probability of bank failures.
This paper presents a portfolio model of financial intermediation in which currency choice is determined by hedging decisions on both sides of a bank’s balance sheet. Minimum variance portfolio (MVP) allocations are found to provide a natural benchmark to estimate the scope for dollarization of bank deposits and loans as a function of macroeconomic uncertainty. Dollarization hysteresis is shown to occur when the expected volatility of the inflation rate is high in relation to that of the real exchange rate. The evidence shows that MVP dollarization generally approximates actual dollarization closely for a broad sample of countries, and policy implications are explored.
"Levy-Yeyati, Martinez Peria, and Schmukler show that systemic risk exerts a significant impact on the behavior of depositors, sometimes overshadowing their responses to standard bank fundamentals. Systemic risk can affect market discipline both regardless of and through bank fundamentals. First, worsening systemic conditions can directly threaten the value of deposits by way of dual agency problems. Second, to the extent that banks are exposed to systemic risk, systemic shocks lead to a future deterioration of fundamentals not captured by their current values. Using data from the recent banking crises in Argentina and Uruguay, the authors show that market discipline is indeed quite robust once systemic risk is factored in. As systemic risk increases, the informational content of past fundamentals declines. These episodes also show how few systemic shocks can trigger a run irrespective of ex-ante fundamentals. Overall, the evidence suggests that in emerging economies, the notion of market discipline needs to account for systemic risk. This paper--a product of the Finance Team, Development Research Group--is part of a larger effort in the group to study market discipline"--World Bank web site.
This paper shows that a central bank, by announcing and committing ex-ante to a bailout policy that is contingent on the realization of certain states of nature (for example on the occurrence of an adverse macroeconomic shock), creates a risk-reducing “value effect” that more than outweighs the moral hazard component of such a policy.
