ABSTRACTThis paper aims to explore the conceptual potential of the Deleuzian notion of the encounter in order to better understand the genealogy of opportunities. We adopt a processual perspective of opportunities. In order to translate this notion to the domain of entrepreneurship, we analysed and interpreted Jean-Marc Vallée’s Dallas Buyers Club. This film follows the creation of the first club in the United States that illegally allowed HIV-positive people to supply themselves with foreign antiretroviral drugs from Mexico or Japan. The article highlights encounters in this process that disturb the entrepreneur’s belief systems and allow him or her to be open to potential opportunity. It finally explores how the encounter may improve our understanding of the political becoming of opportunities within the entrepreneurial process. 相似文献

The nature and magnitude of the economic shocks that have affected the per capita GDP of 16 OECD countries are analyzed over a long period using the outlier method. Strong proof of infrequent large permanent and transitory shocks were found, essentially resulting from the two major wars in the twentieth century, the recession in the 1920s, the Great Depression, among others. We also examine the nature of the output trend by combining different tests of non-stationarity on different GDP series corrected by the outliers detected. It is shown that the per capita GDP series cannot reject the unit root hypothesis in 13 of the 16 countries examined. No conclusion could be drawn for the other countries because the test results were contradictory. 相似文献

This article addresses the issue of optimal patent protection in an economy with a downstream and an upstream sector. The key insight is that higher patent protection in the downstream sector raises the incentives of agents to do R&D in that sector but discourages innovation in the upstream sector because of a market size effect. Hence, higher patent protection in the upstream sector accelerates growth whereas higher patent protection in the downstream sector slows it down. If some innovation is socially desirable, optimal patent protection is necessarily higher in the upstream than in the downstream sector. 相似文献

When the indemnity schedule is contingent on the farmer's price and individual yield, an optimal crop revenue insurance contract depends only on the farmer's gross revenue. However, this design is not efficient if, as is the case with available contracts, the coverage function is based on imperfect estimators of individual yield and/or price. The producer's degree of prudence and the extent of basis risks have important influences on the optimal indemnity schedule. In this broader context, optimal protection is not provided by available U.S. crop insurance contracts and may include combinations of revenue insurance, yield insurance, futures, and options contracts. 相似文献

Markets reacted strongly to the World Trade Center attacks both in Europe and in the United States. The extent of this crisis was difficult to assess at the time, underlining the need for a specific tool to measure the magnitude of financial crises. A first measure was recently proposed and applied to the foreign exchange market by Zumbach et al. (2000a,b ). Their measure relies on an analogy with geophysics; the related index of market shocks (IMS) that we propose here is also the counterpart of the Richter scale used for earthquakes. We apply this measure on the French and the American stock markets to put large market events into perspective. The crisis triggered by the September attacks was actually the worst since 1987, and the ninth worst when compared to major historical ones. 相似文献

We study the local turnpike property for two classes of infinite-horizon discrete-time deterministic maximization problems
which have common applications, e.g., optimal growth theory. We follow a functional-analytic approach and rely on an implicit
function theorem for the space of the sequences which converge to zero. We shall assume the existence of an optimal path which
is not necessarily a steady-state. Relying on material developped in Blot and Crettez (Decis Econo Finance 27:1–34, 2004),
“On the smoothness of optimal paths” Decis Econ Finance, 21:1–34, 2004), we provide conditions under which a variation in
the initial conditions (i.e., capital stock and discount rate) yields an optimal solution which converges toward a reference
solution when time becomes infinite. We also provide new results on bounded solutions of difference equations.
We gratefully thank the editor, Silvano Holzer, and two anonymous referees for remarks and advices on a previous version of

We study the connections between the labour market and the education sector in a matching framework with ex-post wage bargaining. Workers have multidimensional skills and the search market is segmented by technology. Education is a time-consuming activity and determines jointly the scope - or adaptability - and intensity - or productivity - of individual skills. We establish three main results. First, unemployment provides incentives to schooling by raising the need for adaptability. Second, private returns to productivity are below social returns, but no hold-up phenomenon is involved. Third, due to wage and congestion externalities, private returns to adaptability exceed social returns. As a consequence, both over- and under-education may take place in equilibrium. 相似文献

Outsourcing, Imports and Labour Demand 总被引:7,自引:0,他引:7
This paper examines the effects of purchased services and imported intermediate materials on the labour demand for different skills in German manufacturing sectors. We derive and estimate a factor demand system based on the generalised Box–Cox cost function nesting both the normalised quadratic and the translog functional form. We find that the impacts of output and capital growth are more important in explaining the demand for heterogeneous labour than substitution effects between labour and non–labour inputs. Similarly, the increasing use of both imported materials and purchased services is a consequence of output growth rather than input substitution.

The article explores the relevance of a particular approach of the institutionalist movement, régulation theory, to deal with the relationship between the economy and the environment. Régulation theory, which appeared in France at the end of the 1970s, is mainly interested in macroeconomic issues. In contrast, until now it has tended to neglect environmental questions. By taking several key concepts of this theory (accumulation regime, mode of régulation, institutional forms), we have sought to assess its significance vis-à-vis the environmental field. More precisely, from the perspective of establishing an environmental regulationist theory, we propose considering the economic relation to the environment as the articulation of three forms: a transhistorical form, a general capitalist form and a specific capitalist form, the latter being variable in capitalist time and space. We give several illustrations of the variability of the relation to the environment, depending on the different accumulation regimes and the different modes of régulation. Two principal avenues of research are proposed: historical analyses for given economic areas, and comparative analyses relating in particular to different capitalist areas. 相似文献
