Intra-day interest rates are zero. Consequently, a foreign exchange dealer can short a vulnerable currency in the morning, close this position in the afternoon, and never face an interest cost. This tactic might seem especially attractive in times of crisis, since it suggests an immunity to the...

A reduction in inflation can fuel run-ups in housing prices if people suffer from money illusion. For example, investors who decide whether to rent or buy a house by simply comparing monthly rent and mortgage payments do not take into account that inflation lowers future real mortgage costs. We...

Using firm-level data, we provide evidence that, although monetary policy affects real investment, the effect operates differentially: the greater its export intensity the less a firm is affected by tight money. We examine several interpretations and conclude that the impact is transmitted...

We derive new estimates of total wealth, the returns on total wealth, and the wealth effect on consumption. We estimate the prices of aggregate risk from bond yields and stock returns using a no-arbitrage model. Using these risk prices, we compute total wealth as the price of a claim to...

The relative popularity of adjustable-rate mortgages (ARMs) and fixed-rate mortgages (FRMs) varies considerably both across countries and over time. We ask how movements in current and expected future interest rates affect the share of ARMs in total mortgage issuance. Using a nine-country panel...

This paper reviews the monetary transmission mechanism in low income countries (LICs). We use monetary transmission in advanced and emerging markets as a benchmark to identify aspects of the transmission mechanism that may operate differently in LICs. In particular, we focus on the effects of...

We analyze the joint dynamics of religious beliefs, scientific progress and coalitional politics along both religious and economic lines. History offers many examples of the recurring tensions between science and organized religion, but as part of the paper’s motivating evidence we also...

To what extent has Sub-Saharan Africa’s slow economic growth over the past five decades been due to price and trade policies that have discouraged production of agricultural relative to non-agricultural tradables? This paper uses a new set of estimates of policy distortions to relative prices...

We model technological and financial innovation as reflecting the decisions of profit maximizing agents and explore the implications for economic growth. We start with a Schumpeterian endogenous growth model where entrepreneurs earn monopoly profits by inventing better goods and financiers arise...

We develop a stylized model of economic growth with bubbles. In this model, financial frictions lead to equilibrium dispersion in the rates of return to investment. During bubbly episodes, relatively inefficient investors demand bubbles while relatively efficient investors supply them. Because...
