The paper analyses the existence of pure strategy Nash equilibrium in price competition (or Bertrand equilibrium) in a homogeneous product market when costs are strictly convex and proves that if output is demand determined such equilibrium always exists. This paper also characterises such...

The present note develops a model of vertical linkage between the formal and informal credit markets highlighting the presence of corruption in the distribution of formal credit. The existing dominant moneylender, the bank official and the new moneylenders move sequentially. The existing...

We show here, in contrast to recent results, that if firms have different cost functions (that are strictly subadditive), such that the 'monopoly breakeven prices' are different, then in a homogeneous product duopoly there is always a Bertrand equilibrium (either in pure strategies or in mixed...

What is the role of human capital in the regional location of the software industry? Why did policy rate cuts in India not lead to a rapid lowering of the banks' lending rates in the context of the financial crises? How does women's education impact on patrilocal marriage and cultural norms?...

We consider a two good world where an individual i with income mi has utility function u(x,y), where x belongs to [0,infinity) and y belongs {0,1}. We first derive the valuation (maximum price that he is willing to pay for the object) for good y as a function of his income. Then we consider the...

This paper develops a model of determination of the unionized wage in the presence of both collective bargaining and an efficiency wage. The efficiency of each worker is positively related to both the wage and the unemployment rate in the economy. The unionized wage is greater than the...

In this article we provide a brief survey of the literature on ‘scoring auctions’. We start with the benchmark model of the traditional auction theory and then proceed to the literature on scoring auctions. We first discuss the pioneering work of Che (1993) in detail. Then we review...
