What are a country's policy options in the face of emerging technologies development in a global economy? To answer this question, we examine optimal dynamic policies in an open economy where technology is endogenously accumulated through R&D innovation. Our key insight is that a country has...

This paper incorporates firm-level distortions into a Melitz model and characterizes welfare under misallocation. We derive an analogue to the well-known ACR result in an economy with distortions. We highlight a channel through which trade can reduce welfare by exacerbating misallocation. A key...

We study optimal dynamic trade policies in an Eaton-Kortum model with technology diffusion through trade. The process of innovation and diffusion is one in which new ideas are combined with insights from others. Trade thus affects technology by determining the distribution from which producers...

Both conventional wisdom and leading academic research view pork barrel spending as antithetical to responsible policymaking in times of crisis. In this paper we present an alternative view. When agents are heterogeneous in their ideology and in their information about the economic situation,...

We contribute to the debate on the macroeconomic effects of fiscal stimuli by showing that the impact of government expenditure shocks depends crucially on key country characteristics, such as the level of development, exchange rate regime, openness to trade, and public indebtedness. Based on a...

A large empirical literature has found that fiscal policy in developing countries is procyclical, in contrast to high-income countries where it is countercyclical. The idea that fiscal policy in developing countries is procyclical has all but reached the status of conventional wisdom. This has...

On the twentieth anniversary of its inception, the euro has yet to expand its role as an international currency. We document this fact with a wide range of indicators including its role as an anchor or reference in exchange rate arrangements--which we argue is a portmanteau measure--and as a...

Using a novel source of quasi-experimental variation in interest rates, we develop a new approach to estimating the Elasticity of Intertemporal Substitution (EIS). In the UK, the mortgage interest rate features discrete jumps - notches - at thresholds for the loan-to-value (LTV) ratio. These...

We investigate the effect of house prices on household borrowing using administrative mortgage data from the UK and a new empirical approach. The data contain household-level information on house prices and borrowing in a panel of homeowners, who refinance at regular and quasi-exogenous...

Detailed country-by-country chronologies are an informative companion piece to our paper "Exchange Arrangements Entering the 21st Century: Which Anchor Will Hold?," which provides a comprehensive history of anchor or reference currencies, exchange rate arrangements, and a new measure of foreign...
