Facing the challenge of climate change, innovations that imply environmental benefits create business opportunities for entrepreneurs. This paper analyzes innovation capabilities of startups in Cleantech and how the innovation outcomes of those startups develop over time. Based on the Mannheim Foundation Panel and applying propensity score matching, a cohort of 567 Cleantech startups is analyzed and compared with a control cohort of non‐Cleantech startups. We find that startups in Cleantech have, on average, higher technological capabilities compared with all other startups. Our econometric evidence shows that Cleantech startups are more likely to combine existing technology in a novel way. Finally, we find that Cleantech startups develop more market novelties in subsequent years when compared with their control group peers. 相似文献

Established tests for proper calibration of multivariate density forecasts based on Rosenblatt probability integral transforms can be manipulated by changing the order of variables in the forecasting model. We derive order-invariant tests. The new tests are applicable to densities of arbitrary dimensions and can deal with parameter estimation uncertainty and dynamic misspecification. Monte Carlo simulations show that they often have superior power relative to established approaches. We use the tests to evaluate generalized autoregressive conditional heteroskedasticity-based multivariate density forecasts for a vector of stock market returns and macroeconomic forecasts from a Bayesian vector autoregression with time-varying parameters. 相似文献

The Norwegian Consumer Bankruptcy Act was passed 17 July 1992 to give persons with "serious debt problems (. . .) the possibility to gain control over their economy." The Act contains provisions for negotiations between the debtor and the creditors, for court rulings on repayment plans, and for a discharge of the debts not covered by the plan. The origin of the Act was a social welfare approach to the problem of overindebtedness. However, the Act embodies an inherent contradiction in that it also includes moral elements in order to prevent it from exerting a negative influence on the perceived obligation to pay one's debts. This contradiction has given the courts a wide scope of discretion in the application of the Act. As a result, cases are treated differently in different jurisdictions. Some judges put more emphasis on moral evaluations than others. This situation also gives room for strategic action from creditor groups who typically are repeat players in cases of consumer bankruptcy. In this way the more objective, social welfare approach of the Act is undermined. 相似文献

This paper studies the behaviour of Dutch banks. We test the adjustment of banks' balance sheets in times of monetary policy changes during the period 1957–1991. As a reaction to a policy change, banks basically have two alternatives to adjust their net money creation: (1) sell securities in public capital markets, and/or issue long-term liabilities, and (2) change domestic loan supply. If banks opt for the latter a lending channel may be relevant, even in a small open economy with a fixed exchange rate and a high degree of international capital mobility. We test for the effectiveness of both indirect and direct instruments of monetary policy. It turns out that in case of changes in the official interest rate, the volume of bank loans is not affected and that banks display a kind of buffer-stock behaviour by diminishing their publicly traded assets. In situations with quantity restrictions on the growth of net money creation, however, the volume of loans is affected significantly when the quantity restriction is withdrawn thereby fulfilling a necessary condition for the bank lending channel to be effective. 相似文献

Both soft, noncontractible, and hard, contractible, information are informative about managerial ability and future firm performance. If a manager's future compensation depends on expectations of ability or future performance, then the manager has implicit incentives to affect the information. We examine the real incentive effects of soft information in a dynamic agency with limited commitment. When long-term contracts are renegotiated, the rewards for future performance inherent in long-term contracts allow the principal partial control over the implicit incentives. This is because the soft information affects the basis for contract renegotiation. With short-term contracts, the principal has no control over the basis for contract negotiation, and thus long-term contracts generally dominate short-term contracts. With long-term contracts, the principal's control over implicit incentives is characterized in terms of effective contracting on an implicit aggregation of the soft information that arises from predicting (forming expectations of) future performance. We provide sufficient conditions for soft information to have no real incentive effects. In general, implicit incentives not controllable by the principal include fixed effects, such as career concerns driven by labor markets external to the agency. When controllable incentives span the fixed effects of career concerns, the latter have no real effects with regard to total managerial incentives—they would optimally be the same with or without career concerns. Our analysis suggests empirical tests for estimating career concerns that should explicitly incorporate noncontractible information. 相似文献

Although enterprises in the informal food sector require energy to transform, cook and process food, energy-use patterns in this sector are not well understood by policymakers and the local-level authorities who regulate their trading activities. This paper reviews relevant literature and presents empirical data collected in Rwanda, Senegal and South Africa on the use of traditional and modern energy sources by informal food sector operators. Our sample includes male- and female-operated enterprises in the urban centres of three African countries where the informal food sector is important, not only for providing the convenience of affordable and readily prepared meals, but also as a source of income for women and men in developing countries. Multiple fuel-use and energy-stacking strategies are common among informal food enterprises and policy needs to acknowledge this if it is to intervene in ways that will benefit both enterprises and regulators. 相似文献

This paper implements a spatial vector autoregressive model that takes into account both the time and the spatial dimensions
of economic shocks. We apply this framework to analyze the propagation through space and time of macroeconomic (inflation,
output gap and interest rate) shocks in Europe. The empirical analysis identifies an economically and statistically significant
spatial component in the transmission of macroeconomic shocks in Europe. 相似文献

The paper combines insight from new trade theory and R&D-based endogenous growth models to argue that there are ambiguous growth effects of trade liberalization between countries that differ in terms of the size of their home markets. In particular, trade liberalization may reduce R&D incentives in countries with low purchasing power without invoking parallel increases in countries with high purchasing power. The paper also considers the case of imperfect international knowledge spillovers, and demonstrates that complete trade liberalization may affect the growth rate negatively. 相似文献
