This paper introduces finance or credit in the Dixit-Stiglitz-Krugman (DSK) model of international trade. It identifies mechanisms by which finance can affect the main results of the conventional model. The key results are as follows. Perfect credit market does not affect number of varieties or...

Artificial Intelligence (AI) has the potential to significantly impact the income of individuals. Cross-country data shows that introduction of AI is inequality enhancing in developing and less developed countries. In this paper, we attempt to understand the reason for increase in wage...

In this paper we revisit the influential theory of monopolistic competition and optimum product variety as developed by Dixit and Stiglitz (1977) with applications in international trade by Krugman (1979,1980), by modeling fixed and variable costs of production in terms of underlying use of...

This paper explores the role of wage fund as the basic source of credit, capital or finance in a dynamic Ricardian model, which consists of three classes of agents: the workers, the capitalist, and the producers of goods. We introduce and develop an elaborate dynamic wage fund model in the...

Informality of markets is largely perceived as undesirable. Yet, ample evidence suggests that the informal sector contributes substantially in terms of income and employment in the entire developing world. In this paper, tax evaded income is invested in the informal credit market which in turn...

In this paper we revisit the influential theory of monopolistic competition and optimum product variety as developed by Dixit and Stiglitz (1977) with applications in international trade by Krugman (1979,1980), by modeling fixed and variable costs of production in terms of underlying use of...

In many developing economies rate of unemployment is increasing with skill accumulation and thereby leading to underemployment. Our paper offers to look at skill formation as a demand side problem not as a traditional supply side problem and also how skill formation or education affects...

In a general equilibrium model with online, entertainment and informal sectors employing skill, unskilled, and capital, we show that Covid-19 could cause polarization pushing contact-intensive entertainment industry on the brink of collapse while other two survive. Dual roles of factor-intensity...

In this paper, we construct an elaborate general equilibrium model with a continuum of production fragments for an intermediate good, then embed it in a growth model to address the effects of global production fragmentation, vertical specialization and trade on growth and inequality for a small...

In this paper, unlike the conventional wisdom, we demonstrate that the relationship between the size of the market and number of firms would be non-monotonic. While moderate rise in the size would force the local firms to exit and only the foreign firm rules, substantial rise in the size would...
