We quantify the contribution of firm-level technological change to skill demand and aggregate inequality in the presence of imperfect competition in the labor market. We show that skill-biased technological change increases both the firm-level skill ratio and the skill premium, while other...

This study investigates the impact of global price fluctuations on economic welfare in Burkina Faso, with a particular focus on the role of trade intermediaries. Using a computable general equilibrium (CGE) calibrated with a 2019 Social Accounting Matrix (SAM), the analysis incorporates a trade...

This paper studies the adoption of clean technology in an oligopolistic setting, focusing on carbon capture and storage (CCS) in the cement sector. Firms can choose between two technologies: a carbon-intensive ("dirty") technology and a low-carbon ("clean") one. Initially, all firms operate with...

This study constructs a model of exclusive-offer competition between two existing up-stream firms. Under exclusive-offer competition, the upstream firm's profit depends on the rival's exclusive offer. If the rival makes an exclusive offer acceptable for the downstream firm, the upstream firm is...

We study the determination of market power at the firm and industry levels when heterogeneous firms compete for sales to ex ante homogeneous buyers in a market with both directed and random search and free entry of firms that differ in productivity. Search and the distribution of productivity...

By affecting prices and thereby market shares of green and brown firms, product innovations and process innovations influence industry emissions even when they do not directly affect the emission intensity of the innovating firm. Using a differentiated two-stage duopoly, this paper therefore...

This paper develops an analytical model of sequential electricity markets in which renewable and conventional producers compete in two stages. Building on previous work, we introduce risk-averse renewable producers and distinguish between competitive and oligopolistic renewable producers. The...

The main goal of this article is to contribute to the theoretical analysis of international trade under imperfect competition using the Cournot oligopoly model with heterogeneous firms. In particular, our objective is to provide some insights into the role of cost asymmetry in studying the...

We develop a structural framework that allows us to quantify the evolution of aggregate bilateral trade costs and markups over time. With minimal assumptions, we can disentangle aggregate markup and trade cost changes from observed changes in trade flows. We apply our method to trade data...

Using a new administrative dataset, we provide fresh micro-level evidence on firms’ returns to scale (RTS). We employ a new administrative database, iBACH, which contains extensive high-quality annual balance sheet, financial, and demographic information on more than two million non-financial...

We study the role of firm heterogeneity and imperfect competition for global production networks and the gains from trade. We develop a quantifiable trade model with two-sided firm heterogeneity, matching frictions, and oligopolistic competition upstream. More productive buyers endogenously...

Participation in social groups ties members to local communities. Employers can capture these benefits as rents when geographically-specific club goods raise the cost of labor mobility. We measure ties to local clubs using the shares of households identifying with a minority religion, enrollment...

By affecting prices and thereby market shares of green and brown firms, product innovations and process innovations influence industry emissions even when they do not directly affect the emission intensity of the innovating firm. Using a differentiated two-stage duopoly, this paper therefore...

Labor economics often assumes that wages w are equal to the marginal revenue product of labor MRP L. However, recent literature has shown that firms' market power allows them to pay wages substantially below marginal productivity. The markdown (MRP L - w)/w is our preferred measure of firms'...

We estimate a dynamic model of the U.S. space launch industry. The model allows past launches to improve rocket reliability and lower launch costs. It also allows the government to make forward-looking procurement choices. We use the model to analyze policy-relevant issues in the recent history...

The incorporation of increasing returns and imperfect competition into applied general-equilibrium (AGE) models, beginning with Harris (1984), led to much larger welfare effects from changes such as trade liberalization. But the imperfect competition side of these IO developments has often...

This paper studies how product differentiation affects substitution patterns and firms' markups in oligopolistic markets where products are differentiated over multiple attributes and consumers have linear-quadratic preferences. Under these assumptions, the cross-price elasticity between any two...

This paper analyses an electricity market in which a monopolist that employs fossil-fuel base-load and peak-load technologies competes against a fringe of renewable energy (RE) generators. The optimal technology and electricity mix can be decentralised by levying technology-dependent capacity...

Futures contracts have been highly successful financial securities, with substantial trading volumes and active underlying asset markets. In a dynamic market framework, we show that imperfect competition in future spot markets motivates trades in futures contracts in earlier periods. The...

The incorporation of increasing returns and imperfect competition into applied general-equilibrium (AGE) models, beginning with Harris (1984), led to much larger welfare effects from changes such as trade liberalization. But the imperfect competition side of these IO developments has often...

This paper furnishes an inclusive framework to examine the welfare effects of the interventions of multiple policies, and other exterior alterations under imperfect competition and an assertion on particular and .the leading case of the ad valorem taxes. In particular, for the tax pass-through,...

It has long been recognized that competitive considerations play a central role in corporate voluntary disclosure practices. Yet, the ways in which competition and disclosure interact are sensitive to various factors, including both the nature of information and the nature of competitive...
