In this paper we consider the entry and exit of firms in a Ramsey model with capital and an endogenous labour supply. At the firm level, there is a fixed cost combined with increasing marginal cost, which gives a standard U-shaped cost curve with optimal firm size. The costs of entry (exit) are...

We construct investor sentiment of UK stock market using the procedure of principal component analysis. Using sentiment-augmented EGARCH component model, we analyse the impacts of sentiment on market excess return, the permanent component of market volatility and the transitory component of...

The paper presents a human-capital-based endogenous growth, cash-in-advance economy with endogenous velocity where exchange credit is produced in a decentralized banking sector, and money is supplied stochastically by the central bank. From this it derives an exact functional form for a general...

Assuming constant marginal cost, it is shown that a switch from specific to ad valorem taxation has no effect on the critical discount factor required to sustain collusion. This result is shown to hold for Cournot oligopoly as well as for Bertrand oligopoly when collusion is sustained with...

Although non-R&D innovation activities account for a significant portion of innovation efforts carried out across very heterogeneous economies in Europe, how to incorporate them in to economic models is not always straightforward. For instance, the traditional macro approach to estimating the...

We model banks as profit-cum-utility maximizing firms and study, inter alia, bankers’ incentives (optimal effort) and incentive driven productivity following deregulations. Our model puts to test a panel of Nepalese commercial banks which went through deep financial reforms in the recent past....

Distortionary income taxation in a standard New Keynesian model substantially increases the nominal term-premium on long-term bonds relative to a model with lumpsum taxes. Also the empirical level of the nominal term premium can be matched with lower risk-aversion coefficient in case of a model...

We study optimal bidder collusion at first-price auctions when the collusive mechanism only relies on signals about bidders’ valuations. We build on Fang and Morris (2006) when two bidders have low or high private valuation of a single object and additionally each receives a private noisy...

We show that the static duopoly model in which firms choose between exporting and foreign direct investment is often a prisoners' dilemma game in which a switch from exporting to foreign direct investment reduces profits. By contrast, we show that when the game is repeated there is a range of...

There is substantial empirical evidence that innovation is geographically concentrated. Unlike what is generally assumed, however, it is not clear that localised knowledge spillovers provide a theoretically valid explanation for this. Studying spillovers of cost-reducing technology between...
