The paper surveys the types of models producing multiple equilibria in financial markets. It argues that such models are consistent with observed phenomena, such as the greater volatility of financial asset prices than of macroeconomic fundamentals. Alternative explanations are compared with the...

There is increasing recognition that corruption has substantial, adverse effects on economic growth. But if the costs of corruption are so high, why don’t countries strive to improve their institutions and root out corruption? Why do many countries appear to be stuck in a vicious circle of...

We present an extensive analysis of the consequences for global equilibrium determinacy in flexible-price open economies of implementing active interest rate rules, i.e., monetary rules where the nominal interest rate responds more than proportionally to inflation. We show that conditions under...

We analyse optimal discretionary games between a benevolent central bank and a myopic government in a New Keynesian model. First, when lump-sum taxes are available and public debt is absent, we show that a Nash game results in too much government spending and excessively high interest rates,...

Using data for a sample of developing and transition countries, this paper estimates the relationship between government spending on health care and education, and social indicators. Unlike previous studies, where social indicators are used as proxies for the unobservable health and education...

Using monthly data for a set of variables, we examine the out-of-sample performance of various variance/covariance models and find that no model has consistently outperformed the others. We also show that it is possible to increase the probability mass toward the tails and to match reasonably...

This paper analyzes reasons for the high post-war correlations of saving and investment, both across countries and over time. It is concluded that the main reason for the observed high correlations over the recent period is probably government policy

This paper analyzes an economy in which there are no interest-bearing assets, only equity shares. Equilibrium conditions are derived for the case of a closed economy, an open economy with trade in goods only, and finally one with trade in both goods and equity shares. It is shown that the rate...
