In this paper, we are going to reconsider the standard Viner Model [Viner, 1950] however under the premise of firm heterogeneity. By means of a graphical analysis we show that a consideration of the degree of firm heterogeneity is important for an evaluation of a preferential trade agreement....

This paper empirically evaluates the effects of antidumping measures on the exports of protected firms. While antidumping protection raises the domestic sales of the more 'traditional?non-exporting firms on the protected market with about 5%, it negatively affects the firm-level exports of...

This paper uses highly disaggregated trade data to investigate geographic and product diversification patterns across a group of developing nations for the period from 1990 to 2005. The econometric investigation shows that the gravity equation fits the observed differences in diversification...

This paper outlines a simple regression-based method to decompose the variance of an aggregate time series into the variance of its components, which is then applied to measure the relative contributions of productivity, hours per worker, and employment to cyclical output growth across a panel...

This paper documents a puzzling fact, namely that there is a significant negative relation between employment protection legislation and the usage of the intensive margin of labor market adjustments. We then make use of a Real Business Cycle model and introduce search and matching frictions as...

We characterize the solution to the optimal nonlinear income taxation problem if individuals face a minimum hours constraint that gives rise to labor supply responses along the extensive margin. We provide conditions for optimal marginal tax rates to be positive everywhere and derive a formula...

This paper analyzes firm level adjustment of the product mix and its implications for aggregate output growth. Using firm level panel data from Ethiopian manufacturing during the period 1996-2007, it shows that about 30% of firms adjust their 'extensive margin' annually by adding and/or dropping...

In this paper, we investigate the relationship between export performance and economic growth in Russian regions. We propose a methodology for decomposition of export growth into intensive and extensive margins and distinguish between product- and geographic extensive components within extensive...

We adapt the heterogeneous firm trade models of Helpman, Melitz, and Rubinstein (2008) and Lawless (2010) to analyze extensive and intensive trade margins using state-level exports to foreign nations. Our theoretical analysis provides definitive predictions for the effects of changes in fixed...

The present paper examines the effects of the Customs Union (CU) and Free Trade Agreements (FTAs) on Turkey's extensive and intensive margins. For this purpose, using highly disaggregated product-level data at the six-digit product level of Harmonized System, we first decompose Turkey's export...
