Mit der Globalisierung und dem technischen Wandel sind Chancen und Risiken verbunden. Wer profitiert von dem ?konomischen
Wandel und wer geh?rt zu den Verlierern? Welche Probleme ergeben sich aus einer m?glichen Spaltung der Gesellschaft? Wie sollte
die Wirtschaftspolitik auf diese Herausforderungen reagieren? Professor Giacomo Corneo pl?diert für einen „New Deal“.

We analyze the design of optimal regulation of a domestic monopolist that also competes in an unregulated foreign market. We show how foreign activities affect regulation, consumers' surplus, national welfare, and firm's profits. Although expansion in unregulated foreign markets amplifies the distortions that are caused by the regulator's limited information, we also show that allowing the firm to compete abroad does not necessarily harm domestic consumers. We analyze if and when the firm's decision to expand abroad coincides with national interests. 相似文献

Sectors with a long regulatory tradition have recently experienced intense activity by multinationals whose international operations and relocation threats represent a new cause for concern for regulators. I analyze a multinational serving two countries and being regulated by two national authorities. The firm is shown to favor, or cross‐subsidize, the country with a larger stake in the firm's profit, and the linkage among national regulations may induce unexpected effects on outputs. I also analyze a multinational's lobbying decisions and its effects on national regulations. Finally, a credible threat to “fly” away from tough regulators lets the firm obtain larger profits. 相似文献

In a standard model of oligopoly with differentiated products, the existence of an equilibrium at which the first-order conditions for profit maximisation are simultaneously satisfied for all firms is proved and this is done without imposing any restrictions on the demand functions. This is an equilibrium in the following sense: although some firms may not necessarily be maximising their profits, nevertheless if each firm's knowledge of demand is limited to the linear approximation of its own demand curve, then it will believe that it is indeed maximising its profits. 相似文献

We present a detailed analysis of interest rate derivatives valuation under credit risk and collateral modeling. We show how the credit and collateral extended valuation framework presented in Pallavicini et al. [Funding valuation adjustment: FVA consistent with CVA, DVA, WWR, collateral, netting and re-hyphotecation, 2011], and the related collateralized valuation measure, can be helpful in defining the key market rates underlying the multiple interest rate curves that characterize current interest rate markets. A key point is that spot Libor rates are to be treated as market primitives rather than being defined by no-arbitrage relationships. We formulate a consistent realistic dynamics for the different rates emerging from our analysis and compare the resulting model performances to simpler models used in the industry. We include the often neglected margin period of risk, showing how this feature may increase the impact of different rates dynamics on valuation. We point out limitations of multiple curve models with deterministic basis considering valuation of particularly sensitive products such as basis swaps. We stress that a proper wrong way risk analysis for such products requires a model with a stochastic basis and we show numerical results confirming this fact. 相似文献

Growing interest in sustainable transportation systems has driven decision-makers toward policies and investments aimed at promoting cycling, but little to no effort has been made toward incorporating bicycle transport in transport planning models. This study contributes toward this direction by estimating a bicycle route choice model in value-of-distance space from a large sample of 3384 cycling trips that were traced with GPS devices in the Copenhagen Region. The novelty of this study lies in (i) observing cyclists' behavior in a cycling-oriented country, (ii) exploiting rich data about the cycling environment, (iii) estimating the model in value-of-distance rather than preference space, and (iv) not focusing only on preferences for traditional variables (e.g., distance, turns, hilliness, intersections, motorized road characteristics), but also on perceptions and preferences for bicycle facilities (e.g., bicycle lanes, bicycle paths, bicycle traces) and land-use designations (e.g., residential, industrial, sports, scenic areas). The findings from the model show that: (i) cyclists exhibit heterogeneous preferences for avoiding right and left turns, cycling the wrong way, using roundabouts and bridges, and cycling alongside residential and scenic areas; (ii) cyclists dislike cycling on unpaved and hilly surfaces and alongside larger roads; (iii) cyclists have clear perceptions about different types of bicycle facilities, with a preference for bicycle lanes and segregated paths; (iv) cyclists have clear perceptions about land-use designations, with a preference for cycling alongside sports and scenic areas; (v) time-of-day and air temperature contribute to the perceptions of cyclists and their preferences for bicycle facilities and land-use designations. 相似文献

This paper evaluates the welfare effects of the 1986 Tax Reform Act (TRA86). We rely on different welfare metrics, which fully retain preference heterogeneity and are based on different ethical priors. We estimate utility functions with preference heterogeneity on the basis of structural models of family labor supply. Then, using these estimated preferences, we compute and compare different well-being rankings corresponding to different ways of measuring well-being. Finally, we identify the losers and the winners of TRA86, in absolute and relative terms, for each of the welfare metrics. 相似文献
