Measuring the effectiveness of non-price export promotion using a supply-side approach

In this paper we assess the effectiveness of the Market Promotion Program (MPP) in increasing U.S. exports and benefitting U.S. agricultural producers and food processors. Export shipments are linked to producer welfare using Kohli's (1978) profit maximization (GNP function) approach to modeling international trade. Using estimated profit functions in conjunction with a synthetic export demand function for processed agricultural products, we compute changes in farm and food processing sector profits that result from alternative own-price and advertising elasticities of export demand with and without the MPP subsidy. This approach allows us to investigate aggregate welfare effects of nonprice promotion without requiring the difficult task of estimating the export demand effects of market promotion activities for numerous commodities and importing countries.

IPTV(网络电视)广告类型和产品类型的广告效果

在本研究中，从IPTV作为一种新媒体的角度，根据不同的IPTV广告类型和产品类型存在的效果差异进行探索。为此，依据广告类型和产品类型的不同分别进行了4个实验调查，IPTV广告效果测定了广告态度、广告点击意向、产品购买意向。首先，由于IPTV广告种类的不同，使广告效果的差异表现在广告态度和点击意向上；第二，根据产品类型的不同，IPTV广告效果也出现了差异。在广告态度和点击意向及购买意向存在差异的同时，IPTV广告中探索研究比经验型研究显示出更有效的反应；第三，由于广告类型和产品类型的不同，相互作用效果在购买意向上表现了出来。这些为广告中利用IPTV的媒体两面性提供了依据；其次，倡议在广告实行战略中开发能预期对消费者起到积极广告效果的带有图标和字幕的网幅广告；再次，在IPTV广告的制作方面，为探索性的IPTV广告能够诱发更有效的广告效果提供了理论性的依据。

On the Scope for International Tax Cooperation: The Role of Capital Controls

Tax competition between independent authorities is known to lead to inefficient outcomes, implying there is scope for cooperation. In an international framework where the authorities are national governments, the undesirable features of tax competition may alternatively be mitigated by imposing restrictions on international capital flows. Using a two-country model it is shown that capital controls may fully remedy the adverse effects of tax competition and thereby render tax cooperation superfluous. In more general cases, however, capital controls have some undesirable side-effects, leaving room for cooperative actions. Moreover, the mere option of imposing capital controls may promote the implementation of tax cooperation.     

Risk Aversion and the Bid–Ask Spread

This paper studies the properties of bid and ask prices posted by a monopolistic market maker, without parametric assumptions about the utility function of the market maker or about the probability distribution of the return of the risky asset. We first prove that the two prices can be higher or lower than the expected value of the asset, and that the spread is decreasing in the initial wealth when the market maker exhibits decreasing absolute risk aversion. We conclude by some examples illustrating the fact that almost all shapes can be obtained for the bid–ask spread (as a function of the inventory) depending on the probability distribution of the payment of the risky asset.     

Does the liquidity effect guarantee a positive term premium?

This paper examines the liquidity effect and the term structure in two versions of the limited participation model—an imperfect information model and an adjustment cost model. With a discrete-state solution approach, I find a striking contrast: while the imperfect information model successfully generates the liquidity effect and the positive term premium seen in the data; the adjustment cost model replicates only the liquidity effect. This is because the adjustment cost that drives the liquidity effect in the adjustment cost model also creates an adjustment cost effect, which leads to a negative term premium.     

Patent Protection, Transnational Corporations, and Market Structure: A Simulation Study of the Indian Pharmaceutical Industry

This study examines the role of patent protection on the behavior of transnational corporations and market structure in the Indian pharmaceutical industry. The method of analysis is the calibration of a theoretical model to firm-level data from two therapeutic groups of the Indian pharmacy market, and a simulation analysis asking the hypothetical question of what the market structure would be if India granted patent protection to pharmaceutical products. The model developed for the simulation analysis explicitly accounts for the complex demand structure for pharmaceutical goods that results from the presence of therapeutic substitute drugs, and product differentiation among chemically equivalent drugs.     

Competition Effects of Supermarket Services

This article investigates the competition effects of supermarket services using fluid milk as a case study. A simultaneous equation model for services and price competition is estimated with scanner data from fifteen supermarket chains using two alternative measures of services, namely store size and principal components of in-store services. Empirical results show that increasing services results in economies of scope, greater supermarket chain-level demand, lower price elasticity of demand, and enhanced market power, leading to higher milk prices and quantity sold. We conclude that, as result of service competition, supermarkets differentiate themselves from competitors and successfully attract less price-sensitive consumers.
