Common wisdom suggests that entry reduces profits of the incumbentfirms. On the contrary, we show that if the incumbents differ in marginal costs and theentrants behave like Stackelberg followers, entry may benefit the incumbents who arerelatively cost efficient while it always hurts the cost...

This paper compares Bertrand and Cournot equilibria in a horizontallydifferentiated duopoly market with non-tournament R&D competition. We consider thatsuccess in R&D is uncertain. We show that whether firms invest more under Cournotcompetition or Bertrand competition is ambiguous and depends on...

Once a new technology has been invented, there is a credible threat of imitationwhen patents are long and imitation cost is low. When imitation is credible, the innovator hasan incentive to postpone technology adoption for relatively high cost of imitation. Thepossibility of licensing eliminates...

The paper proves that in two-player logit form symmetric contestswith concave success function, commitment to a particular strategydoes not increase a player's payo, while in contests with more thantwo players it does. The paper also provides a contest-like game inwhich commitment does not...

Real effective exchange rate volatility is examined for 90 countries using monthlydata from January 1990 to June 2006. Volatility decreases with openness tointernational trade and per capita GDP, and increases with inflation, particularlyunder a horizontal peg or band, and with terms-of-trade...

The fact that members of an immigrant community may have different demographiccharacteristics, or may have different tastes, to the indigenous population, may manifestitself in differences in saving behaviour. In addition, depending on their ethnicbackground, there could be differences among the...

This paper contributes to the literature by introducing the nexus between financial constraints and thecapital-labour uptake and by considering the capital-labour ratio to overcome the problems that haveplagued investment literature -regarding the investment-cash flow sensitivity of constrained...

In this paper we develop a simple procedure which delivers tests for the pres-ence of a broken trend in a univariate time series which do not require knowledgeof the form of serial correlation in the data and are robust as to whether theshocks are generated by an I(0) or an I(1) process. Two...

In this paper, we aim to model the vertical relation between retailers and suppliersin the food industry whereby retailers exercise seller power in their relation with consumersand buyer power in their relation with producers. We then evaluate the degree of pricetransmission, relative to the...

We consider a simple random walk process, a special case ofthe Martingale model, which exhibits a deterministic break in its drift term,for instance, from positive to negative. This particular example can be aplausible model for a time series on exchange rates which displays a persistentcurrency...
