We present a two-good, two-country overlapping generations model where emissions arise from production and each country has a domestic emission permit system. When one country unilaterally reduces her cap on emissions, her output available for domestic and foreign consumption diminishes more...

Germany like many other European countries subsidize commuting by granting the right to deduct commuting expenses from the income tax base. This regulation has often been changed and has regularly been under debate during the last decades. The pros (e.g. causing efficiency gains with respect to...

The objective of this paper is to examine efficiency, distributional, environmental (CO2 emissions) and spatial effects of increasing different kinds of transport subsidies discriminating between household types, travel purposes and travel modes. The effects are calculated by applying a...

Housing affordability is the main policy challenge for many large cities in the world. Zoning changes, rent control, housing vouchers, and tax credits are the main levers employed by policy makers. But how effective are they at combatting the affordability crisis? We build a new framework to...

Many of the world's major cities have attracted a flurry of out-of-town (OOT) home buyers. Such capital inflows affect house prices, rents, construction, labor income, wealth, and ultimately welfare. We develop an equilibrium model, calibrated to the typical U.S. metropolitan area, to quantify...

We consider the optimal education policies of a small economy whose government has a limited budget. Initially, the economy is closed and the government chooses its education policy to maximize welfare under autarky. Then the economy trades with the rest of the world. Lastly, the government...

This paper reviews the most significant recent developments in the theory of trade agreements. The paper offers an integrated approach to evaluating trade agreements, and uses the approach to present results on preferential and multilateral trade agreements. The paper identifies also several...

Quantitative results from a large class of international trade models depend critically on the elasticity of trade with respect to trade frictions. We develop a simulated method of moments estimator to estimate this elasticity from disaggregate price and trade-flow data using the Ricardian...

This paper proposes a model where heterogeneous firms choose whether to undertake R&D or not. Innovative firms are more productive, have larger investment opportunities and lower own funds for necessary tangible continuation investments than non-innovating firms. As a result, they are...
