Many studies investigate the relationship between R&D and patents applying knowledge production functions. Using aggregated R&D may underestimate the productivity of ‘R’, as mainly ‘R’ but not ‘D’ leads to patents. Disaggregating ‘R’ and ‘D’ shows a significant premium of ‘R’ towards patenting.  相似文献

An explicit relationship between innovations in the spot exchange rate and innovations in its driving variables is derived in the context of the ‘asset market theory’ of the exchange rate. The relationship forms a theoretical basis for regression results in ‘news’ form that have been reported in the literature.  相似文献

Preparation     
A product set of pure strategies is a prep set (‘prep’ is short for ‘preparation’) if it contains at least one best reply to any consistent belief that a player may have about the strategic behavior of his opponents. Minimal prep sets are shown to exist in a class of strategic games satisfying minor topological conditions. The concept of minimal prep sets is compared with (pure and mixed) Nash equilibria, rationalizability, minimal curb sets, and persistent retracts.  相似文献

Mixed estimation with an informative prior can be regarded as a form of least squares estimation with an enlarged data set. The relationship between such additional ‘pseudo data’ and the sample data is studied.  相似文献

Bauer's views on vicious circles, the ‘widening’ gap between rich and poor countries, central planning, foreign aid and the appeal of Marxism in less developed countries are summarised. There is a discussion and summary of an appropriate analysis of the issues raised by Bauer. Attention is concentrated on the evidence related to a ‘widening’ gap, the potential failures of the price mechanism and the effects of foreign aid. It is suggested that Bauer's analysis is superficial, even though this may also be true of some he criticises, and that the case for aid remains strong.  相似文献

We incorporate endogenous time preference in a simple Diamond-type economy with production and analyze the resulting dynamics both for the competitive and command equilibrium. We assume an individual's rate of time preference is decreasing in consumption (decreasing marginal impatience) and show that this intuitively more appealing assumption is consistent with a stable, non-trivial competitive equilibrium. Analysis of the competitive equilibrium indicates that the observed ‘non-convergence’ of cross-country per capita income could partially be explained by cross-country differences in ‘innate patience’. Examination of the local dynamics around the ‘optimal’ solution suggests that this particular preference structure exhibiting diminishing marginal impatience may generate endogenous business cycle phenomenon.  相似文献

Taken the growth of the underground-economy for granted, this paper develops an explanation for its existence that is different from those usually provided. Presupposing a ‘generalized norm of reciprocity’ that guides the relationship between individuals and the state, it is argued that a reduction of certain payments from the government to individuals, e.g. in order lower budget deficits, may lead to an erosion of loyalty with possibly “catastrophical consequences” on overall economic activity: a situation that may ask for different policy measures than usually thought of as being appropriate.  相似文献

The dynamics of persistence in US inflation   总被引:1,自引:0,他引:1  
Using a recently developed time-series approach, we show that post-WWII US inflation became highly persistent during the ‘Great Inflation’ period, and then switched back to a low persistence process during 1984, and has remained stationary until the present day.  相似文献

This essay formalizes the model of international growth advanced by W. Arthur Lewis in his 1979 Nobel Prize address and by Ragnar Nurkse in the 1950's. Both of them employed the model to support their respective cases for pursuit of a ‘balanced growth’ strategy by the LDC's. The purpose of the formalization undertaken here is to examine the theoretical consequences for the secular ratio of LDC to MDC incomes as the Lewis-Nurkse growth process unfolds. The paper explores whether or not growth in Lewis-Nurkse fashion must mean persistent poverty for the LDC's. In addition, the formalization provides an explicit characterization of economic ‘dependence’.  相似文献

The ‘wage space’, which is defined as the sum of price inflation and labour productivity growth, has played a major role as an indicator of allowable wage increases in the post-war wage negotiations in the Netherlands. This paper shows that: (a) wages and the wage space are co-integrated; (b) the deviation between wages and the wage space may act as an error correction term in the wage equation when both variables are identified as I(2); and (c) political consensus and the threat of labour conflicts (rather than actual strike activity) may be identified as the ‘mechanism’ behind this error correction in the wage equation.  相似文献

Food production chains can be organised in a variety of ways. Conventional ‘industrial’ agricultural practices are based on advanced breeding techniques and major inputs of chemical fertilisers and pesticides. Food produced in this way is transport-intensive, requires high-energy processing, relies on modern retailing systems and demands high-tech kitchens. Many argue that the industrialised systems should be dismantled and replaced with alternative methods of agriculture, food processing and distribution that emphasise social and environmental sustainability. This paper looks at the environmental and social sustainability of different strategies for food systems by analysing the whole chain of production, processing, distribution and consumption activities of the production of frozen peas, a vegetable that is ‘symbolic’ of modern food systems and the UK diet.  相似文献

This paper incorporates limited asset markets participation in dynamic general equilibrium and develops a simple analytical framework for monetary policy analysis. Aggregate dynamics and stability properties of an otherwise standard business cycle model depend nonlinearly on the degree of asset market participation. While ‘moderate’ participation rates strengthen the role of monetary policy, low enough participation causes an inversion of results dictated by conventional wisdom. The slope of the ‘IS’ curve changes sign, the ‘Taylor principle’ is inverted, optimal welfare-maximizing discretionary monetary policy requires a passive policy rule and the effects and propagation of shocks are changed. However, a targeting rule implementing optimal policy under commitment delivers equilibrium determinacy regardless of the degree of asset market participation. Our results may justify Fed's behavior during the ‘Great Inflation’ period.  相似文献

Commitment is problematic because one sometimes pursues it against one’s interest. To solve it, the paper proposes a distinction between ‘non-binding’ and ‘binding’ commitments. Non-binding commitment is about ambition, such as becoming a great chef, which bolsters welfare in the pecuniary sense as well as self-respect. In contrast, ‘binding commitment’ is about honesty. While it diminishes welfare, it augments self-integrity. The neoclassical view reduces both commitments to interest, while the multiple-self approach separates both commitments from interest. The separation permits the confusion of sentimental fools, who enter commitments without regard to interest, with rational sentimentalists, who take interest into consideration.  相似文献

This paper evaluates the use of environmental ‘adders’ as a regulatory instrument. It evaluates their likely performance in meeting the policy objective of social costing given the changes in the electric utility industry's structure and in environmental policy since the efforts to estimate these costs were initiated. The prognosis is largely negative — suggesting that environmental adders are inconsistent with the increased competition already underway in the utility industry, as well as with the trend toward greater use of true market-based approaches to environmental policy that are not subject to detailed economic regulation.  相似文献

Established corporations are often at a disadvantage vis à vis technology-based entrepreneurial firms when it comes to generating and adapting to radical technological and business-model innovation. Consequently, industrial corporations increasingly wanted to participate in the financial or strategic success of start-ups. The tool of choice for many corporations was Corporate Venture Capital (CVC). CVC had already seen two waves of popularity in the USA when it was introduced in Germany in the early 1990s. This development is often assumed to have come to a halt in 2001, when so-called ‘New Economy’ spiraled into decline.This paper analyzes central attributes of strategy, investment and organization of the CVC units active in Germany in 2000 and 2003. We find evidence for a continuation of strong CVC activity in Germany. We differentiate between CVC units that were a) active at both points in time, i.e. ‘survivors’ b) those that have closed down since 2000, i.e. ‘losers’ and c) those that were founded after 2000, ‘new entrants’. The comparison of the characteristics allows us to make inferences for the use of CVC.  相似文献

How do people value freedom of choice? Drawing on economics and psychology the paper provides an hypothesis and empirical evidence on how individuals may value freedom of choice and derive utility from it. It is argued that the degree of perceived control that individuals have over choice – a construct known as the locus of control in psychology – regulates how we value freedom of choice. People who believe that the outcome of their actions depends on internal factors such as effort and skills (the ‘internals’) have a greater appreciation of freedom of choice than people who believe that the outcome of their actions depends on external factors such as fate or destiny (the ‘externals’). We find some evidence in support of this hypothesis using a combination of all rounds of the World and European Values Surveys. A variable that measures freedom of choice and the locus of control is found to predict life satisfaction better than any other known factor such as health, employment, income, marriage or religion, across countries and within countries. We show that this variable is not a proxy of happiness and measures well both freedom of choice and the locus of control. ‘Internals’ are found to appreciate freedom of choice more than ‘externals’ and to be happier. These findings have important implications for individual utility, social welfare and public policies.  相似文献

We consider a game where agents can synchronize or stagger their decisions. We compare the outcomes of both timing patterns, and show that spillovers and strategic interactions are crucial for such a comparison. A typology used in industrial organization, distinguishing four cases (‘Fat-Cat’, ‘Top Dog’, Lean and Hungry’, ‘Puppy Dog’), allows us to compare the actions taken in the staggered variant and in the synchronized one. The staggered variant exhibits cycles and players are both better-off when there are strategic complementarities between them. A timing game is then set-up so as to endogenize the choice between the two variants we study.Two examples are developed: (i) Bertrand competition and (ii) a wage setting game when there are two monopoly unions in two interrelated firms. We show that the staggering of price decisions generates counter-cyclical mark-ups in the first example, and the staggering of wage decisions generates cycling output in the industry in the second example.  相似文献
