This paper presents evidence about how research and development (R&D) expenditures affect corporate cash holdings in European country groups that differ in their innovation capacity. In theory, one can expect intangible investments such as R&D to result in higher cash stocks than fixed investments, particularly because intangible capital is less suitable as collateral for obtaining external funds. The relationship can be expected to be particularly strong in innovative countries. These countries carry out a relatively high proportion of cutting-edge R&D, which tends to be particularly risky and may be associated with substantial gestation lags before becoming productive. These features tend to increase firms' precautionary cash holdings. To investigate this issue in a European context, we examine different groups of countries that are clustered based on differences in their innovative capacity. Our estimation results confirm a positive relation between changes in R&D investment and changes in cash holdings, whereas changes in fixed investment do not appear to be related to changes in cash positions. The impact of changes in R&D on cash tends to be higher for country groups characterized by a high level of innovative capacity than for countries with moderate levels of innovative capacity. However, the differences across country groups are less pronounced than expected. 相似文献

In the aftermath of the market liberalization reforms, interventions in developing countries shifted toward building institutions. One of such interventions is the introduction of commodity exchanges. The theoretical justification is that commoditization reduces the high transaction costs associated with the information and enforcement problems characterizing agricultural markets of these countries. However it is not known whether these potential gains are transmitted to the various markets along a value chain. By taking the Ethiopian Commodity Exchange (ECX) as a case, this paper examines the impacts of the introduction of the commodity exchange in transmitting price signals along the coffee value chain (world‐export‐auction‐producer prices). We found that both the speed and symmetry of transmission remains weak even after the launch of ECX. At each level, the market chain was found to favor buyers. This implies that not only the country's gains from export are sub‐optimal, the cumulative burden is on the millions of smallholder farmers who are located at the bottom of the chain. In a context where local agricultural markets remain traditional and export markets barely competitive, the introduction of the commodity exchange will have limited impacts in improving the performance of markets in transmitting price signals. Other policy measures to further liberalize both local and export markets are required. 相似文献

We develop a general stochastic model of directed search on the job. Directed search allows us to focus on a Block Recursive Equilibrium (BRE) where agents' value functions, policy functions and market tightness do not depend on the distribution of workers over wages and unemployment. We formally prove existence of a BRE under various specifications of workers' preferences and contractual environments, including dynamic contracts and fixed-wage contracts. Solving a BRE is as easy as solving a representative agent model, in contrast to the analytical and computational difficulties in models of random search on the job. 相似文献

Stimulating Strategically Aligned Behaviour Among Employees 总被引:1,自引:0,他引:1

Strategically aligned behaviour (SAB), i.e. employee action that is consistent with the company's strategy, is of vital importance to companies. This study provides insights into the way managers could promote such behaviour among employees (who can be managers as well) by stimulating employee motivation, by informing employees, and by stimulating the development of their capabilities. The results of surveys conducted in three organizations suggest that, first, perceived efforts by management aimed at motivating and informing employees (both managers and non-managers), and at developing their capabilities, each are related to SAB. Second, among the perceived efforts to stimulate motivation among employees, providing a rationale for the strategy and an open communication climate have a stronger relationship with SAB than participation in decision making and supportiveness. Third, the perceptions of the different types of managerial effort are related to each other. For this reason, the efforts have direct as well as indirect relationships to SAB. Fourth, each of the perceived efforts seems to be complementary to the others, in the sense that the relationship of one type of effort to SAB is stronger when other types of effort are perceived to be higher. 相似文献

This paper studies 40 years of evolution in the German laser industry, which developed in the context of strong foreign competition.
Key characteristics found in the U.S. laser industry are also present in Germany. There is sustained entry into the industry,
and neither a shakeout nor first-mover advantages of early entrants are observed. Similar to the U.S. industry, spin-offs
from existing laser firms have been more long-lived than have been academic startups. An analysis of the spin-off process
indicates the importance of specific capabilities acquired at the parent firm.

The shortage of studies on spatial spillovers of capital subsidy policies is rather surprising, considering that such policies are usually designed to generate spatial externalities. We propose a new framework that allows positive agglomeration effects to be contrasted with the negative cross-sectional substitution and the crowding-out effect. The global evaluation of the ATT and the spillover parameters shifts the spotlight from the policy effect on subsidised firms to the global effect of capital subsidy policies on the targeted territory. The empirical evaluation of a policy in Italy mainly directed towards small- and medium-sized firms shows that the impact on investments, turnover and employment is positive and large, but is negative on TFP. However, the employment growth is partially determined to the detriment of the untreated firms. 相似文献

Financial crises in emerging market countries appear to be very costly: both output and a host of partial welfare indicators decline dramatically. The magnitude of these costs is puzzling both from an accounting perspective – factor usage does not decline as much as output, resulting in large falls in measured productivity – and from a theoretical perspective. With the aim of resolving this puzzle, we present a framework that allows us to do the following. First, we account for changes in a country's measured productivity during a financial crisis as the result of changes in the underlying technology of the economy, the efficiency with which resources are allocated across sectors, and the efficiency of the resource allocation within sectors, driven both by reallocation amongst existing plants and by entry and exit. Second, we measure the change in the country's welfare resulting from changes in productivity, government spending, the terms of trade, and a country's international investment position. We apply this framework to the Argentine crisis of 2001 using a unique establishment level dataset and we find that more than half of the, roughly, 10 percent decline in measured total factor productivity can be accounted for by deteriorations in the allocation of resources both across and within sectors. We measure the decline in welfare to be of the order of one‐quarter of one year's gross domestic product. 相似文献

The incentives to conduct basic or applied research play a central role for economic growth. How does increasing early innovation appropriability affect basic research, applied research, innovation and growth? In a common law system an explicitly dynamic macroeconomic analysis is appropriate. This paper analyzes the macroeconomic effects of patent protection by incorporating a two-stage cumulative innovation structure into a quality-ladder growth model with endogenous skill acquisition. We focus on two issues: (a) the over-protection versus the under-protection of intellectual property rights in basic research; (b) the evolution of jurisprudence shaping the bargaining power of the upstream innovators. We show that the dynamic general equilibrium interactions may seriously mislead the empirical assessment of the growth effects of IPR policy: stronger protection of upstream innovation always looks bad in the short- and possibly medium-run. We also provide a simple “rule of thumb” indicator of the basic researcher bargaining power. 相似文献
