Procurement and Predation: Dynamic Sourcing from Financially Constrained Suppliers

This paper studies the interaction between financially constrained and financially strong firms on a procurement market. It characterizes and discusses a procurement agency’s optimal response when faced with financially asymmetric firms. By considering a dynamic setting, both present and future consequences and incentives are taken into account

Tourism Immiserization: Fact or Fiction?

Tourism plays a major part in the development strategies of both developing and developed countries because of the alleged potential of generating foreign exchange, economic growth and welfare enhancement (Sinclair and Stabler, 1997; Sinclair, 1988). Consequently, in several countries a considerable amount of resources is allocated to further promote the tourism sector in a hope of reaping more economic benefits. However, it is still debatable whether tourism is beneficial for the tourist-receiving country or not. While empirical studies (Adams and Parmenter, 1994; Zhou et al., 1996, Baaijens et al., 1998; Blake, 2000; Blake et. al., 2003; Dwyer et al., 2003), argue that tourism expansion is beneficial to the economy, theoretical studies (Copeland, 1991; Chen and Devereux, 1999; Hazari and Nowak, 2003; Hazari et al., 2003; Nowak et al., 2003) posit that tourism expansion can be immiserizing. This paper critically reviews the theoretical and empirical literature to identify the sources via which tourism expansion can benefit or harm the economy. The issues are then empirically investigated using a CGE model for Mauritius to identify the conditions under which tourism expansion can be immiserizing.Tourism, Immiserization, Welfare, Economic growth

SHOULD COUNTRIES PROMOTE FOREIGN DIRECT INVESTMENT?

This paper examines whether policies to promote foreign direct investment (FDI) make economic sense. The discussion focuses on whether existing academic research suggests that the benefits of FDI are sufficient to justify the kind of policy interventions seen in practice. For small open economies, efficient taxation of foreign and domestic capital depends on their relative mobility. If foreign and domestic capital are equally mobile internationally, it will be optimal for countries to subject both types of capital to equal tax treatment. If foreign capital is more mobile internationally, it will be optimal to have lower taxes on capital owned by foreign residents than on capital owned by domestic residents. Absent market failure, there is no justification for favouring FDI over foreign portfolio investment. In practice, countries appear to tax income from foreign capital at rates lower than those for domestic capital and to subject different forms of foreign investment to very different tax treatment. FDI appears to be sensitive to host-country characteristics. Higher taxes deter foreign investment, while a more educated work force and larger goods markets attract FDI. There is also some evidence that multinationals tend to agglomerate in a manner consistent with location-specific externalities. There is weak evidence that FDI generates positive spillovers for host economies. While multinationals are attracted to high-productivity countries, and to high-productivity industries within these countries, there is little evidence at the firm or plant level that FDI raises the productivity of domestic enterprises. Indeed, it appears that plants in industries with a larger multinational presence tend to enjoy lower rates of productivity growth over time. Empirical research thus provides little support for the idea that promoting FDI is warranted on welfare grounds. Subsidies to FDI are more likely to be warranted where multinationals are intensive in the use of elastically supplied factors, where the arrival of multinationals to a market does not lower the market share of domestic firms, and where FDI generates strong positive productivity spillovers for domestic agents. Empirical research suggests that the first and third conditions are unlikely to hold. In the three cases we examine, it appears that the second condition holds, but not the first or third conditions. This suggests that Brazil’s subsidies to foreign automobile manufacturers may have lowered national welfare. Costa Rica appears to have been prudent in not offering subsidies in the case of Intel. There clearly is a need for much more research on the host-economy consequences of FDI. The impression from existing academic literature is that countries should be sceptical about claims that promoting FDI will raise national welfare. A sensible approach for policy makes in host countries is to presume that subsidizing FDI is unwarranted, unless clear evidence is presented to support the argument that the social returns to FDI exceed the private returns.

Mixed contracts for the newsvendor problem with real options

In this paper we consider the newsvendor model with real options. We consider a mixed contract where the retailer can order a combination of q units subject to the conditions in a classical newsvendor contract and Q real options on the same items. We provide a closed form solution to this mixed contract when the demand is discrete and study some of its properties. We also offer an explicit solution for the continuous case. In particular we demonstrate that a mixed contract may be superior to a real option contract when a manufacturer has a bound on how much variance she is willing to accept.Newsvendor model; real options; discrete demand; mixed contract

The structure of the optimal combined sourcing policy using capacity reservation and spot market with price uncertainty

This contribution focuses on the cost-effective management of the combined use of two procurement options: the short-term option is given by a spot-market with random price, whereas the long-term alternative is characterized by a multi period capacity reservation contract with fixed purchase price, reservation level and capacity reservation cost. Considering a multiperiod problem with stochastic demand, the structure of the optimal combined purchasing policy is derived using stochastic dynamic programming.Capacity reservation, spot market, purchasing policy, supply contracts, stochastic inventory control

Law & Economics Perspectives on Electricity Regulation

This paper first reviews some of the main contributions of the new institutional economics to the analysis of the process of competitive transformation of network industries. It shows that neoinstitutional analysis is complementary to the microeconomics of rational pricing, since it accounts for the decisive role of an institutional framework adapted to new transactions. It emphasizes the importance of the political reform process, which draws on the conditions of attractiveness and feasibility to define an initial reorganization of property rights in these industries. The paper then analyzes in this light some of the main challenges ahead for electricity regulation: the question of investment in generation capacities and the link to long term contracts, the regulation of wholesale market power, the support to Renewable Energy Sources for Electricity (RES-E) and the design of new regulatory authorities.Electricity Markets; New Institutional Economics; Law & Economics

From the Theory of the Firm to FDI and Internalisation: A Survey

This paper surveys recent contributions on the Internalisation issue, based on different theories of the firm, to show how the make-or-buy decision, at an international level, has been assessed through the opening up of the “black box” - traditionally explored by the theorists of the firm – and the simultaneous endogenization of the market environment – as in the International Economics tradition. In particular, we consider three Archetypes – Grossman-Hart-Moore treatment of hold-up and contractual incompleteness, Holmstrom-Milgrom view of the firm as an incentive system, Aghion-Tirole conceptualisation of formal and real authority in organisations – and show how they have been embedded in industry and general equilibrium models of FDI to explain the boundaries of global firms.FDI, Internalisation, International Economics, Incomplete contracts
