This paper analyzes how the affiliation of a venture capital firm affects the deal terms for innovative entrepreneurial ventures. We develop a theory to explain the advantages of independent and bank-affiliated venture capital funds for entrepreneurs. We assume that independent venture capital firms provide better support quality while bank-affiliated firms are less financially constrained. The entrepreneur selects the optimal contract by trading-off these characteristics. The model allows several empirically testable predictions concerning the nature of projects financed by either type of venture capital firm. Entrepreneurs should seek capital from independent or affiliated venture capitalists contingent on the degree of sophistication of their project, their liquidation value, the importance of expected management support, and the remaining time to fundraising.  相似文献

We build on a one parameter family of weighting schemes arising from \(L^2\)-constrained portfolio optimization problems. The parameter allows to fine tune the trade-off between the volatility and the diversification of the portfolio. We propose two criteria in order to determine two unique portfolios: the first criterion requires that no weights be negative while the second one imposes a target diversification which is median between full concentration and full diversification. Both portfolios are empirically compared to classical benchmarks. The first one behaves very much like other popular Long-Only weighting schemes while the second displays a more aggressive profile, while generating moderate turnover. We also discuss implementation issues, as well as estimation related problems.  相似文献

The extension of rotation lengths in forests has been proposed as an option for increasing carbon storage and contributing to climate change mitigation. This paper presents the results of a case study conducted on forests located in the southwest of France. The aim of this research was to assess the cost effectiveness of a subsidy/tax system on carbon fluxes. First, it is shown that such a mechanism leads forest owners to extend rotation lengths. However, cost effectiveness analysis shows that: (1) marginal social costs are more expensive than the private marginal costs of carbon sequestration; (2) marginal costs are higher when carbon stocks are discounted, ranging from 170.1 €/tC to 719.8 €/tC with discounted carbon stocks; and from 38.8 €/tC to 78.4 €/tC with undiscounted carbon stocks; (3) marginal costs are in the range of measures of the social value of carbon for France; (4) marginal costs increase with timber prices and increase with discount rate.  相似文献

This paper analyzes the geography of seat capacity at Spanish airports between 2001 and 2008. Concentration and deconcentration patterns for different markets have been identified. For this purpose, we use the Herfindahl-Hirschman Index (HHI), the Concentration Ratio (CR) and the Lorenz curve. From our analysis, we conclude that seat capacity follows a deconcentration pattern due to the growth of low-cost carriers at small- and medium-sized Spanish airports. This is in line with earlier studies for Europe as a whole. Intercontinental seat capacity still remains very much concentrated in Madrid and, to a lesser extent, in Barcelona. However, new strategies by long-haul airlines bypassing the primary European hubs foster the deconcentration of seat capacity in the Asian and North American markets. In the case of Spain, the recent liberalization of the EU-US market may become an important enabler of such network strategies, e.g., Delta has operated a route from Valencia to New York-JFK since 2009. In other intercontinental markets, capacity is more and more concentrated in Madrid. We highlight the restructuring of Iberia’s network as an important factor behind the increasing dominance of Madrid in intercontinental markets.  相似文献

We provide an extension of the explicit solution of a mixed optimal stopping–optimal stochastic control problem introduced by Henderson and Hobson. The problem examines whether the optimal investment problem on a local martingale financial market is affected by the optimal liquidation of an independent indivisible asset. The indivisible asset process is defined by a homogeneous scalar stochastic differential equation, and the investor's preferences are defined by a general expected utility function. The value function is obtained in explicit form, and we prove the existence of an optimal stopping–investment strategy characterized as the limit of an explicit maximizing strategy. Our approach is based on the standard dynamic programming approach.  相似文献

Although a rich body of research provides insights to understanding stigma within the marketplace, much less is known regarding its direct corollary, privilege. We posit that this void is problematic as it may inadvertently support and legitimate existing socio-political arrangements which inhibit consumer wellbeing and marketplace equality. The present study addresses this gap by offering a theoretical understanding of privilege within the marketplace. Using a Foucauldian approach to privilege and power, we draw on the discursive perspective on legitimation to critically investigate the contentious debate over the inclusion of halal meat at a popular burger chain in France. In light of French political secularism (laïcité), we demonstrate how power discursively operates through narratives on rights and moral responsibility to constitute, defend and challenge a certain state of privilege within the marketplace. Our resulting theoretical discussion extends existing studies on marketplace equality and the growing body of literature related to the “marketization of religion”.  相似文献

Nonprofit organizations (NPOs) are subject to multiple pressures from their stakeholders. Stakeholders are at the same time the target of the organization's mission, the evaluators, the providers of resources and the demanders. This article is an essay that defends reciprocal perception as a managerial tool. The proposed intellectual path leads to the revalorization of stakeholder perception as a very useful practical and scientific tool for the management and study of NPOs. However, perception has limitations that the introduction of the concept of reciprocity can address.  相似文献

This paper presents stylized facts concerning the spot intra-daily foreign exchange markets. It first describes intra-daily data and proposes a set of definitions for the variables of interest. Empirical regularities of the foreign exchange intra-daily data are then grouped under three major topics: the distribution of price changes, the process of price formation and the heterogeneous structure of the market. The stylized facts surveyed in this paper shed new light on the market structure that appears composed of heterogeneous agents. It also poses several challenges such as the definition of price and of the time-scale, the concepts of risk and efficiency, the modeling of the markets and the learning process.  相似文献

The U.S. economic development in the 19th century was characterized by the westward movement of population and the accumulation of productive land in the West. This article presents a model of migration and land improvement to identify the quantitatively important forces driving these phenomena. The conclusion is that the decrease in transportation costs induced the westward migration, whereas population growth was responsible for the investment in productive land.  相似文献

How do people experience the platform-mediated job search process? We explore this question based on a sample of in-depth interviews (n = 20) with low-qualified, unemployed Spanish job seekers. Our main finding shows that the ways they use Information and Communication Technologies negatively impact their engagement in online job search activities. Based on our findings, we develop a framework of online job search discouragement revolving around crafting online profiles, applying for jobs, reviewing application statuses and integrating the tensions these activities carry for the experience and the outcome of the platform-mediated job search.  相似文献
