We introduce and analyze a model in which agents observe sequences of signals about the state of the world, some of which are ambiguous and open to interpretation. Instead of using Bayes' rule on the whole sequence, our decision makers use Bayes' rule in an iterative way: first to interpret each...

We present a two-armed bandit model of decision making under uncertainty where the expected return to investing in the "risky arm'' increases when choosing that arm and decreases when choosing the "safe'' arm. These dynamics are natural in applications such as human capital development, job...

We explore the effect of foreign direct investment on economic growth in developing countries, distinguishing between mergers and acquisitions (“M&As”) and “greenfield” investment. A simple model underlines that, unlike greenfield investment, M&As partly represent a rent accruing to...

In this paper we offer an explanation why a poor majority does not necessarily expropriate a rich minority. We present a dynamic model in which individuals are willing to accept an unequal distribution of income in the current period if they are sufficiently optimistic about their future...

This paper studies how removing barriers to competition in the nontraded goods sector affects the current account, the real exchange rate, and factor prices in a small open economy. We show that the expansion of the nontraded sector that results from a deregulation shock is associated with an...

Does official aid pave the road for private foreign investment or does it suffocate private initiative by diverting resources towards unproductive activities? In this paper we explore this question using data for a large number of developing and emerging economies. Controlling for countries?...

Recent studies on the growth effects of exchange rate regimes offer a wide range of different, sometimes contradictory results. In this paper, we systematically compare three prominent contributions in this field. Using a common data set, a common specification and common estimation methods, we...

The paper explains the negative correlation between developing countries' per capita incomes and measures of political risk by relating a government's decision to tax foreign investors to distributional interests in the host country's population. Using a dynamic general-equilibrium model in...
