The size distribution of the domains of US-patented technological knowledge obeys an exponential law, revealing a disproportionable concentration of progress among larger domains. Our analyses suggest that this phenomenon is explained by a combination of two factors. First, domains’ trajectories of growth have inherently different potentials. Second, differences in domains’ potentials are magnified by a mechanism—domains’ self-hybridization—endogenous to the process of knowledge growth. Our results show that in addition to being stable, the observed distribution of technological progress is likely to arise under very general conditions. 相似文献

Abstract In the critical arena of public management and policy debates several schools currently try to make sense of governance structures and processes, although one has so far had the strongest impact in terms of academic and policy influence in particular in the United Kingdom: network governance. Network governance has been associated with Stakeholder Capitalism – as represented for instance by the European (usually German) social-democratic settlement – and as the direct opposite of the New Public Management (as the epitome instead of Shareholder Capitalism). In this essay it will be argued that the alleged novelty of the reforms being currently implemented under the aegis of the ‘modernization’ or (network) governance rhetoric (by the Blair government, for instance) must be questioned, since they are the direct inheritors of the NPM tradition. Through the development of a multiparadigmatic model of ethical and organization theories it will be shown that alternatives to network governance are not only thinkable but also (institutionally) practicable. 相似文献

In this paper, we present a model of the financial resource curse (i.e., episodes of abundant access to foreign capital coupled with weak productivity growth). We study a two‐sector (i.e., tradable and non‐tradable) small open economy. The tradable sector is the engine of growth, and productivity growth is increasing with the amount of labor employed by firms in the tradable sector. A period of large capital inflows, triggered by a fall in the interest rate, is associated with a consumption boom. While the increase in tradable consumption is financed through foreign borrowing, the increase in non‐tradable consumption requires a shift of productive resources toward the non‐tradable sector at the expenses of the tradable sector. The result is stagnant productivity growth. We show that capital controls can be welfare‐enhancing and can be used as a second‐best policy tool to mitigate the misallocation of resources during an episode of financial resource curse. 相似文献

Emission Trading Systems (ETSs) are today regarded as the pillar of market‐based environmental policies in many countries. This paper studies the impact of an ETS on the dynamics of the market made up of two types of firms: clean and dirty. Using an evolutionary context, we study how the share of clean firms evolves at different parameter values, such as increasing values of the permits’ price floor, and show that an ETS can have positive effects on the diffusion of the clean technology. However, numerical simulations show that under specific parameter values the opposite result may emerge with clean firms leaving the market. 相似文献

This paper investigates the two‐way relationship between deep integration and production networks trade. We capture deep integration with a set of indices constructed in terms of policy areas covered in preferential trade agreements. We estimate an augmented gravity equation to investigate the impact of deep integration on production networks trade. The results show that on average, signing deeper agreements increases production networks trade between member countries by almost 12 percentage points. In addition, the impact of deep integration is higher for trade in automobile parts and information and technology products compared with textile products. To analyse whether higher levels of network trade increase the likelihood of signing deeper agreements, we follow the literature on the determinants of preferential trade agreements. The estimation results show that, after taking into account other PTA determinants, a ten percentage increase in the share of production network trade over total trade increases the depth of an agreement by approximately 6 percentage points. In addition, the probability of signing deeper agreements is higher for country pairs involved in North–South production sharing and for countries belonging to the Asia region. 相似文献

Price Stability in Open Economies 总被引:6,自引:0,他引:6
This paper studies the theoretical conditions under which price stability is the optimal policy in a two-country open-economy model with imperfect competition and price stickiness. Special conditions on the levels of country-specific distortionary taxation and the intratemporal and intertemporal elasticities of substitution need to be satisfied. These restrictions apply to both cooperative and non-cooperative settings. Importantly, we show that cooperative and non-cooperative solutions do not coincide despite market completeness and producer currency pricing. We study the conditions under which quadratic approximations of single countries' welfare can be correctly evaluated by relying only on log-linear approximations of the equilibrium conditions. 相似文献

We analyse the pricing and informational efficiency of the Italian market for options written on the most important stock index, the MIB30. We report that a striking percentage of the data consists of option prices violating basic no‐arbitrage conditions. This percentage declines when we relax the no‐arbitrage restrictions to accommodate the presence of bid/ask spreads and other frictions but never becomes negligible. We also investigate the informational efficiency of the MIBO and conclude that option prices are poor predictors of the volatility of MIB30 returns. This conclusion is robust to a number of statistical and sampling methods.

The organisation of health care differs widely across Europe. Access to services, financing schemes, incentives for better care, and administrative efficiency are challenges that are being dealt with in a variety of ways. Are insurance-based systems the best solution for balancing resources and services or are national health funds preferable? Does the introduction of competition fulfil high hopes for better service at lower costs? What are the relative advantages and drawbacks of central and local management of health care? 相似文献
