In this paper, we aim at investigating from a game‐theory perspective whether trade liberalization can promote a collusive two‐way trade. We show that, under Cournot competition, economic integration is anti‐competitive if collusive trade is a possible outcome of the repeated game; under price competition, the likelihood of collusive trade is a necessary but not sufficient condition for trade liberalization to be pro‐competitive. Furthermore, we show that economic integration may increase the scope for collusion irrespective of the firms’ strategic variable.  相似文献

In a well-known essay first published in 1953, Goodwin analyzed the dynamic adjustment of quantities and prices to long-run equilibrium values, in a set ofn ‘Walrasian’ markets. He treated the crossed adjustment of prices and quantities as a linear Hamiltonian vector field. In more recent work, Goodwin introduced non-linear perturbations in his multi-sectoral adjustment model. He assumed that real consumption depends non-linearly on relative prices. This paper shows the following: (1) Goodwin's behavioural hypotheses are compatible with the assumption that agents maximize; (2) if the dynamic process is Hamiltonian, then symplectic coordinate changes are essential tools of analysis; (3) if the real wage is rigid and returns to scale are not constant, then the Hamiltonian model can generate chaotic transients or, in extreme cases, pure chaotic motions.  相似文献

This study provides empirical evidence on the role of universities’ technological transfer (TT) activities in the Italian manufacturing sector, with particular attention to the food industry. Using the UniCredit-Capitalia database (2008 UniCredit-Capitalia. 2008. Decima Indagine Sulle Imprese Manifatturiere Italiane. Rapporto Corporate. [Google Scholar]) for firms and data from the Ministry of Education, University and Research (MIUR) to obtain the university TT indicator, we estimate a probit model to assess the effect of universities’ TT activities on a firm’s likelihood to innovate. The role of proximity in knowledge spillovers from TT activities is also investigated. Results show that university TT activities seem to stimulate food industry firms innovation and the impact appears significantly higher than for the manufacturing sector. Moreover, the effect of TT activities on innovation appears to be geographically bounded. As regards policy implications, this study provides two insights which may help promote innovation in the food sector. First, the factors that influence innovative capability in the food sector are different from those in other sectors, suggesting the need for sector specific instruments for promoting innovation. Second, science is important in the food industry and this raises questions about the policy of mainly considering high-tech industries when promoting a closer relationship between firms and universities.  相似文献

Firms specialized in two different sectors lobby to induce the government to subsidize the type of education complementary to their production. Lobbying is endogenous. We show that, if lobbying is not costly, both sectors will lobby in equilibrium and the education policy will induce the same skill composition that would be chosen by the social planner. However, if lobbying is costly and there is sufficient asymmetry between the sectors, only one sector will exert pressure on the policy‐maker in the attempt to direct resources toward the type of education required by its production. Which sector will engage in lobbying depends on relative size, productivity, and price. We also provide some preliminary evidence that lobbying activity by firms may influence the production of skills needed by those firms.  相似文献

A seemingly mild assumption of the standard alternating offers bargaining model under risk is that the breakdown event is not strictly worse than the worst agreement. When this assumption is relaxed the structure of the equilibrium set of agreements changes in an interesting way. We analyse the effect of disagreement on equilibrium, and relate our result to a class of outside option models. Journal of Economic Literature Classification Number: C78.  相似文献

In this study, we extend recent attempts to clarify the role of antecedents of absorptive capacity in realising purposive inflows of external knowledge in the biopharmaceutical industry. By assuming that internal R&D resources contribute to absorptive capacity as a multidimensional concept, we propose a framework for the integrated analysis of the interactions between the different antecedents of absorptive capacity and inbound open innovation of biopharmaceutical firms. Our analysis relies on a set-theoretic approach and uses fuzzy-set qualitative comparative analysis (fsQCA) to study a set of selected Italian biopharmaceutical firms. The analysis reveals that biopharmaceutical companies with a diversified R&D business domain and an extended entrepreneurial scientific network are likely to adopt an inbound open innovation strategy.  相似文献

The paper presents an empirical investigation of the extent to which exchange rate movements affect export prices in the leading European countries. By extending the model proposed by Kasa (1992) to a context of monopolistic competition, an export price equation has been derived that allows us to clearly identify the effects of nominal exchange rate movements on the exporters' profit margins and therefore on his prices. This equation has then been estimated with reference to five different products (beer, car tyres, truck tyres, aluminium foil and cars) and six markets (United States, Germany, France, Italy, United Kingdom and Spain). The results show that the pass-through is more likely to occur and larger in absolute value for the less differentiated products, for which markets can plausibly be assumed to be more competitive. In line with previous empirical findings, the German and US markets are the ones in which it is most difficult for exporters to modify their prices expressed in local currency.  相似文献

In this article, using the data of 2008, we try to describe the impact of scale and product differentiation in 282 European banks. While evidence of the economies of scale is less clear, the results obtained using a translogarithmic function system show that significant economies of scope do exist even for new banking products like derivatives.

Background: Tuberous sclerosis complex (TSC) is a multi-system genetic disorder in which renal manifestations occur in ~50% of children and 80% of adults. Since these often present alongside other manifestations, renal TSC is likely to incur significant costs. This study aims to quantify healthcare resource use (HCRU) and costs for renal TSC patients in the UK.

Methods: TSC patients in the Clinical Practice Research Datalink (CPRD) linked to Hospital Episodes Statistics were identified from January 1987June 2013. Clinical data were extracted over the entire history and costs were reported over the most recent 3-year period. HCRU was compared with a matched comparator cohort. Incremental costs were reported and the key cost drivers by primary manifestation category were identified by regression modeling.

Results: A total of 79 renal TSC patients were identified with manifestations including chronic kidney disease stage 3–5 (with prevalence increasing with age) and renal angiomyolipoma. Renal TSC patients consistently reported greater HCRU than the comparator. Inpatient hospitalizations were more frequent for renal TSC patients (3.2 vs 1.6), but length of stay was comparable; however, 70.9% of renal TSC patients recorded no kidney-related procedures ever and averaged <1 test per year in the 3-year period. Average costs for renal TSC patients were nearly 3-fold greater than the comparator (£15,162 vs £5672). Costs increased with additional manifestation categories (£3600: only renal; £27,531: renal with ≥4 additional manifestation categories [25% of patients]). Additional nervous system and dermatology/psychiatric manifestations significantly (p?Conclusions: Renal TSC patients have greater HCRU than the general CPRD population, likely to result from progression of renal disease and additional manifestations; however, surveillance for disease progression appears to be deficient. Inadequate monitoring may contribute to a lack of co-ordinated care and increased healthcare-associated costs. Efforts should be made to follow the TSC guidelines to effectively monitor and treat patients.  相似文献
