The Paper provides a reconciliation of Lucas’ paradox, based on fixed setup costs of new investments. With such costs, it does not pay a firm to make a ‘small’ investment, even though such an investment is called for by marginal productivity conditions. Using a sample of 45 developed and...

In this survey, we focus on key mechanisms through which liquidity and financial shocks affect major types of capital flows. We focus on a few models that examine the role of asymmetric information, liquidity preferences, limited enforcement, and incomplete markets on the composition of capital...

A common feature for developing countries that have experienced a sharp drop in inflation without large output losses is the extensive use of capital controls. This study shows that capital controls significantly improve the sacrifice ratio. This element contributes to the explanation of small...

In the political debate people express the idea that immigrants are good because they can help pay for the old. The paper explores this idea in a dynamic political-economy setup. We characterize sub-game perfect Markov equilibria where immigration policy and pay-as-you-go (PAYG) social security...

We study a mechanism through which strong creditor protection affect positively the level, and negatively the volatility, of the aggregate stock market price. In a Tobin-q model with liquidity and productivity shocks, two channels are at work: (1) Creditor protection raises the stock value in a...

The paper analyzes the effect of the generosity of the welfare state on the skill composition of immigrants. We develop a parsimonious model in which the effect of an increase in the generosity (and taxes) of the welfare state on the skill composition of immigrants under free migration is...

The Paper develops a model with lumpy setup costs of new investment, which govern the flows of FDI. Foreign investment decisions are two-fold: whether to export FDI and, if so, how much. The first decision is governed by total profitability considerations, whereas the second is governed by...

Skilled migrants typically contribute to the welfare state more than they draw in benefits from it. The opposite holds for unskilled migrants. This suggests that a host country is likely to boost (respectively, curtail) its welfare system when absorbing high-skill (respectively, low-skill)...

Foreign direct investment (FDI) is observed to be a predominant form of capital flows to low- and middle-income countries with insufficiently developed capital markets. This paper analyses the problem of channelling domestic savings into productive investment, in the presence of asymmetric...

This paper proposes a methodology for computing effective average tax rates using national accounts and revenue statistics, and applies it to construct time-series of tax rates for the seven largest industrialized countries. The resulting tax rates are consistent with available estimates of...
