In his book on 'Market Microstructure' Spulber presented some strange results with respect to the impact of the substitutability parameter in an intermediation model with differentiated products and inputs. Intuitively, effects in the product and the input market should be similar: if firms...

This paper investigates the effect of product differentiation on the real and financial decisions of a publicly-owned firm, competing <InlineEquation ID="IEq1"> <EquationSource Format="TEX">$$\grave{a}$$</EquationSource> </InlineEquation> la Cournot with another privately-owned firm. The results show that the degree of product differentiation affects the stock price coefficients...</equationsource></inlineequation>

This paper considers the effects of trade policy-tariffs and quotas-when importing is done by competitive traders who are identical ex ante but differ ex post. We show that the standard equivalence results no longer hold and the conventional ranking of tariffs and quotas is turned on its head:...

This paper examines how import competition from different origins and the presence of product differentiation affect market power of Swedish manufacturing firms during the 1990s. Applying Roeger’s method (1995), I perform the empirical analysis based on detailed firm-level data and estimate an...

Using firm-level data for Estonia for the years 1997-2005, we analyze the impact of international competition on firm dynamics, considering both firm closedown and product switching. We contribute to the literature in two important ways: (1) this is the first paper to study the determinants of...

In a North-South vertically differentiated duopoly, we derive equilibrium government policies towards parallel imports (PIs). By incorporating strategic interaction at the policy-setting stage and the product market, the model sheds new light on (i) the effects of PI policies on pricing behavior...

This paper explores the hypothesis that the unresponsiveness of export pricing to exchange rate fluctuations may be partially the result of hedging activities by trading agents due to foreign exchange volatility (EV) to eliminate exchange risk. In essence, hedging against foreign exchange...

This study considers the impact of labour and product market characteristics on Research and Development (R&D) activity in the North East. This study extends the literature on regional R&D by focusing on potential strategic relationships between relative firm size, market structure and crucial...

This paper examines the effect of counterfeit goods in a world where consumers are differentiated by level of income and innovation is quality enhancing. Counterfeit goods are defined as products with the same characteristics as “originals”, but of lower quality. The effect of imitation on...

This paper explores the link between quality, cost and concentration. Using concentration and cost data and product quality indicators for 2,244 products in over eighty industries in 1997 and 2002 in the US, a two-stage, ordered probit, random effects estimation explores the impact of...
