How likely is trade liberalization to produce efficiency gains in the presence of imperfect competition, scale economies, and higher-than-average wages in the modern sectors -- all common features of developing economies? These features create a potential conflict to the extent that traditional...

The most cost-effective policies for achieving CO2 abatement (e.g., carbon taxes) fail to get off the ground politically because of unacceptable distributional consequences. This paper explores CO2 abatement policies designed to address distributional concerns. Using an intertemporal numerical...

Aging populations in advanced economies are placing ever-increasing demands on government spending in the form of old-age benefits. Economies that have promised substantially more benefits than they have made provision to finance are heading into a prolonged era of fiscal stress. Unresolved...

Continuous time is a superior representation of both the economic and climate systems that Integrated Assessment Models (IAM) aim to study. Moreover, continuous-time representations are simple to express. Continuous-time models are usually solved by discretizing time, but the quality of a...

Government policies that are not intended to address environmental concerns can nonetheless distort prices and affect firms' emissions. We present an analytical general equilibrium model to study the effect of distortionary subsidies on factor prices and on environmental outcomes. We model an...

How large economic stimuli generate individual and aggregate responses is a central question in economics, but has not been studied experimentally. We provided one-time cash transfers of about USD 1000 to over 10,500 poor households across 653 randomized villages in rural Kenya. The implied...

This paper explores the potential impacts on both China and other major countries of possible mega trade deals. These include the Trans-Pacific Partnership (TPP), the Regional Comprehensive Economic Partnership (RCEP), and various blocked deals. We use a numerical 13-country global general...

During the Great Recession, U.S. unemployment benefits were extended by up to 73 weeks. Theory predicts that extensions increase unemployment by discouraging job search, a partial equilibrium effect. Using data from the large job board CareerBuilder.com, I find that a 10% increase in benefit...

This paper analyzes the effects of environmental policy on employment (and unemployment) using a new general-equilibrium two-sector search model. We find that imposing a pollution tax causes substantial reductions in employment in the regulated (polluting) industry, but this is offset by...

Job security provisions are commonly invoked to explain the high and persistent European unemployment rates. This belief has led several countries to reform their labor markets and liberalize the use of fixed-term contracts. Despite how common such contracts have become after deregulation, there...
