This paper studies the design of sin taxes when firms exercise market power. We outline an optimal tax framework that highlights how market power impacts the efficiency and redistributive properties of sin taxation, and quantify these effects in an application to sugar-sweetened beverage...

Taking account of sinks credits as agreed in Bonn and Marrakech, this paper illustrates how market power could be exerted in the absence of the US ratification under Annex 1 trading and explores the potential implications of the non-competitive supply behavior for the international market of...

The paper studies human capital accumulation over workers' careers in an on the job search setting with heterogenous firms. In renegotiation proof employment con- tracts, more productive firms provide more training. Both general and specific training induce higher wages within jobs, and with...

Firms market power may exacerbate income inequality. We investigate this relationship among firms in Latin America and the Caribbean (LAC), where this phenomenon remains understudied. We use firm-level data for formal firms in 16 countries in LAC and 31 peer economies with similar levels of GDP...

Using establishment-level data from the World Bank Enterprise Survey, we assess the market power of exporting firms across 16 countries in Latin America. Leveraging information on export destinations, as well as exchange rate and price data, we construct exchange rate-driven shocks to the...

It has been shown in prior research that cost effectiveness in the competitive emissions permit market could be affected by tacit collusion or price manipulation when the corresponding polluting product market is oligopolistic. We analyze these cross market links using a Stackelberg model to...

Using a structural VAR analysis, we document that an increase in government purchases raises private consumption, total factor productivity (TFP) and the real wage. This poses a puzzle for both neoclassical and New-Keynesian models. We extend a standard New-Keynesian model to allow for skill...

We use a dynamic factor model to consider if real wage growth in the US, UK and Germany at different percentiles of the distribution can be explained by factors that are common across countries or specific to each country. Our results suggest that common factors explain a large proportion of the...
