Since the publication by Williamson (1968) of his seminal paper on antitrust there has been a growing recognition by regulators of the need to assess trade-offs between merger-related efficiency gains and merger-induced increases in market power. This paper addresses that need by presenting a...

This article aims at explaining the financial crises Turkey experienced in the last decade through a random effects logit model which incorporates 26 macroeconomic, political, and financial sector variables. Evidence emerges that the only significant variablesare current account/GDP, fiscal...

We analyze tick-by-tick data, the most high frequency data available, of yen–dollar exchange rates with focus on the direction of up or down price movement. We propose a non-linear logit model to describe a non-trivial probability structure, apparently invisible from the price change itself,...

When the sample size is small compared to the number of cells in a contingency table, maximum likelihood estimates of logit parameters and their associated standard errors may not exist or may be biased. This problem is usually solved by “smoothing†the estimates, assuming a certain...

Two-way trade in (almost) homogenous products has ambiguous welfare effects if entry is restricted. We examine Swedish imports of bottled water to investigate whether transport cost losses from trade outweigh the partial equilibrium gains from trade (stronger competition and more brands to...

Share equations play an important role in applied economic research, notably in marketing and demand analysis. Both market shares and budget shares have been used as dependent variables in econometric models which were partly motivated by microeconomic theory. However attempts of econometricians...
