We use a novel enterprise survey to gauge the relationship between saving instruments and entrepreneurial reinvestment. We show that while most informal saving practices are not associated with a lower likelihood of reinvestment when compared with formal saving practices, there is a significantly lower association of saving within the household with the likelihood of reinvesting profits than other savings form, most importantly, formal saving forms. This result is robust to the model specification and controlling for a large array of variables including district‐level fixed effects. We also provide empirical tests to address reverse causation and omitted variable concerns. Our work contributes to the debate on the implications of different saving instruments in developing countries and expands the entrepreneurial financing constraints literature by focusing on internal rather than external funding constraints. 相似文献

The aim of standardization is to make sure that different batches of a drug do not vary in their potency. With most drugs this can be done by chemical methods, for a certain number of drugs however biological methods are still necessary. The best procedure to standardize a drug is to use a standard preparation. In this lecture it is discussed which demands must be made upon standard and the criterion. The measurement of the pyrogenic activity of drugs is discussed as an example. 相似文献

We study arbitrage opportunities in diverse markets as introduced by Fernholz (J Math Econ 31:393–417, 1999). By a change of measure technique we are able to generate a variety of diverse markets. The construction is based on an absolutely continuous but non-equivalent measure change which implies the existence of instantaneous arbitrage opportunities in diverse markets. For this technique to work, we single out a crucial non-degeneracy condition. Moreover, we discuss the dynamics of the price process under the new measure as well as further applications.Both authors gratefully acknowledge financial support by the National Centre of Competence in Research “Financial Valuation and Risk Management” (NCCR FINRISK).

Small and Medium Enterprises Across the Globe 总被引:1,自引:0,他引:1
This paper analyzes the relationship between the relative size of the small and medium enterprise (SME) Sector and the business
environment in 76 countries. The paper first describes a new and unique cross-country database that presents consistent and
comparable information on the contribution of the SME sector to total employment in manufacturing and GDP across different
countries. We then relate the importance of SMEs and the informal economy to indicators of different dimensions of the business
environment. We find that several dimensions of the business environment, such as lower costs of entry and better credit information
sharing are associated with a larger size of the SME sector, while higher exit costs are associated with a larger informal
economy.

Do exporters really pay higher wages? First evidence from German linked employer-employee data 总被引:1,自引:0,他引:1
Many plant-level studies find that average wages in exporting firms are higher than in non-exporting firms from the same industry and region. This paper uses a large set of linked employer-employee data from Germany to analyze this exporter wage premium. We show that the wage differential becomes smaller but does not completely vanish when observable and unobservable characteristics of the employees and of the workplace are controlled for. For example, blue-collar (white-collar) employees working in a plant with an export-sales ratio of 60% earn about 1.8 (0.9) % more than similar employees in otherwise identical non-exporting plants. 相似文献

Exponential Hedging and Entropic Penalties 总被引:13,自引:0,他引:13

We solve the problem of hedging a contingent claim B by maximizing the expected exponential utility of terminal net wealth for a locally bounded semimartingale X . We prove a duality relation between this problem and a dual problem for local martingale measures Q for X where we either minimize relative entropy minus a correction term involving B or maximize the Q -price of B subject to an entropic penalty term. Our result is robust in the sense that it holds for several choices of the space of hedging strategies. Applications include a new characterization of the minimal martingale measure and risk-averse asymptotics. 相似文献

Toward a theory of repeat purchase drivers for consumer services 总被引:1,自引:0,他引:1

The marketing discipline’s knowledge about the drivers of service customers’ repeat purchase behavior is highly fragmented.
This research attempts to overcome that fragmented state of knowledge by making major advances toward a theory of repeat purchase
drivers for consumer services. Drawing on means–end theory, the authors develop a hierarchical classification scheme that
organizes repeat purchase drivers into an integrative and comprehensive framework. They then identify drivers on the basis
of 188 face-to-face laddering interviews in two countries (USA and Germany) and assess the drivers’ importance and interrelations
through a national probability sample survey of 618 service customers. In addition to presenting an exhaustive and coherent
set of hierarchical repeat-purchase drivers, the authors provide theoretical explanations for how and why drivers relate to
one another and to repeat purchase behavior. This research also tests the boundary conditions of the proposed framework by
accounting for different service types. In addition to its theoretical contribution, the framework provides companies with
specific information about how to manage long-term customer relationships successfully.
