This paper considers the Web as a big data container that can be used by Technology Observatories and administrations to track emerging issues and more specifically emerging technologies. It considers information that is available on the Internet for free from different sources, and proposes a framework that can be useful to characterise them and to detect patterns of dissemination. This framework is made up of 30 metrics obtained from different kinds of sources (general web, patents, scholars?…). Some of them are obtained directly as the number of hits retrieved by queries on a search engine, and other ones calculated by means of ratios. This paper contains the development of a complete case that utilises this framework to characterise emerging technologies included in the well-known Hype Cycle for Emerging Technologies, in this case the 2015 release1 and to analyze patterns of dissemination of these technologies on the Internet.  相似文献

The paper uses a calibrated general-equilibrium model to quantify the welfare impact of trade liberalization—and compute the optimal tariff structure—for Costa Rica when trade-policy-induced foreign direct investment and international capital taxation with credits are present. It shows that complete trade liberalization reduces Costa Rica's welfare, as it leads to an outflow of capital and loss of tax revenue which more than offset the efficiency gains from an enhanced resource allocation. The optimal tariff structure for the Costa Rican economy turns out to be a mixture of relatively small import tariffs and subsidies.  相似文献

This study investigates gender occupational attainment and earnings differentials in El Salvador and Costa Rica at the end of the 1980s. During this decade, El Salvador experienced a civil war and an economic depression. Costa Rica was also mired in a recession in the early 1980s, but programs adopted in the mid-1980s led to rapid economic recovery. It is found that the gender pay gap in El Salvador is 30.4% and 23.6% in Costa Rica. The intercountry difference in the gap disappears after accounting for high gender differences in occupational attainment and hours worked in El Salvador.  相似文献

In this article we examine how R&D networking affects an organization's innovative output. Using empirical data on 419 research organizations in transgene plant research over a 20-year period, we test several hypotheses relating their sociometric position in an R&D network to their innovative output. Attention is paid to the relative importance of in-house versus collaborative research. Least squares dummy variable models are used to analyze cross-sectional data across different time periods. The results show that (1) an organization's “network embeddedness” positively influences its innovative output; whereas (2) involvement in collaborative R&D has a curvilinear effect on innovative performance.  相似文献

This article connects two salient economic features: (i) Fiscal shocks have asymmetric effects across business cycle phases (Gechert, Horn, & Paetz, 2019); (ii) the unemployment-output trade-off is time varying and may be unstable. The intertwined dynamic behaviour of fiscal deficit shocks and the unemployment-output trade-off is studied in this article using a time-varying parameter (TVP) vector autoregression (VAR) with stochastic volatility techniques applied to the analysis of data from Canada, France, Germany, Japan, Spain, Sweden, United Kingdom and the United States of America. We confirm the trade-off heterogeneity across country, and its time-varying nature across time, showing in addition its fluctuation around a long-run reference value. We document significant short-run impacts of fiscal shocks on the unemployment-output trade-off which, based on the experience of the Global Financial Crisis, becomes larger in periods of economic turmoil. Policy-wise, the rebalancing of public finances may have unexpected adverse effects on job creation if implemented during slumps, precisely when the labour market sensitivity with respect to the performance of the product market is likely to be more acute. This message is particularly relevant in the aftermath of the Covid-19 pandemic.  相似文献

The development of human tissue engineered technologies, located in the context of wider debates around the governance of biotechnology, raises important issues. This paper explores these issues by examining theoretical approaches to the regulation of risk, the limits of technical risk assessment and implications of scientific uncertainty in this area. We consider broader social concerns and how these shape contemporary debates relating to the sourcing and use of human tissue-engineered technologies. We examine the emergence of a new regulatory ‘regime’ in Europe and the social shaping of a regulatory space between medicinal products, medical devices and biologics where these innovative products may be situated. Reporting on recent policy initiatives and a survey of regulatory authorities in Europe, we analyse the ways in which public trust in these technologies may be engendered, providing insight into public participation in policy debate and relations between industry and the regulatory state at national and European levels.  相似文献

Abstract This paper uses an equilibrium search and matching model to study Canada’s sectoral labour adjustment in 2002–2006 during an increase in global commodity prices and exchange rate appreciation. I estimate economically significant adjustment costs for the aggregate economy in this episode and demonstrate that difficulty in transferring skills between jobs for individual workers can be an important contributor to these aggregate costs. The analysis also demonstrates that the level of unemployment benefits impacts the economy’s sectoral composition, its aggregate productivity, and the speed of its adjustment to shocks.  相似文献

Following the recent global financial crisis, questions about the mechanisms that can help countries cope with large shocks have resurfaced. This paper examines the role of the exchange rate regime in explaining how emerging market economies fared in the recent global financial crisis, particularly in terms of output losses and output rebound. After controlling for regime switches during the crisis, using alternative definitions for pegs, and taking account of other likely determinants, we find that the growth performance for pegs was not different from that of floats during the crisis. The picture is different for the recovery period 2010–2011, as pegs appear to be faring worse, with growth recovering more slowly than floats. These results suggest an asymmetric effect of the regime during and recovering from the crisis. We also find that proxies of the trade and financial channels are important determinants of growth performance during the crisis, while only the trade channel appears important for the recovery thus far.  相似文献

This paper presents an analysis of the effect of remittances on the current account in developing and emerging economies, incorporating an assessment of the extent to which exchange rate regimes impact the relationship. The main findings suggest that there is a positive effect of remittances on the current account contemporaneously, but that the lagged effect is negative, which could be indicative of the existence of some underlying mechanisms characteristic of the Dutch disease phenomenon. In addition, the results show that a more flexible exchange regime dampens the contemporaneous positive effect that remittances have on the current account. The paper, therefore, asserts that policymakers face trade‐offs pertaining to the use of exchange rate policy in managing the effects of remittances on the current account, which should be given due consideration when such policy choices are made.  相似文献

Drawing on the structurationist notion of ‘technologies-in-practice’, this article analyses the different types of technological actions that users perform, after technological change, in order to keep a declining technology alive over time. The research question of the article is: How do technologies-in-practice based on the application of new technology hamper the creative destruction of old technology? The case study of ham radio technology and amateur radio operators is explored. The results of the investigation support the development of a technology-in-practice ‘experimentation’ and four inductive research propositions.  相似文献

In this study, we place green innovation in a broader technology development, commercialisation and distribution context to test hypotheses in three areas: (1) the internal vs external drivers of green innovation; (2) the effect of green innovation on business performance; and (3) the role of channel structures (the degree to which producers sell directly to consumers or businesses) in making green innovation more productive in terms of business performance. To test our hypotheses, data from an international survey among 123 wineries is used. Our results suggest that internal drivers, i.e. environmental management and quality management in particular, play a greater role than external drivers (e.g. government and regulatory pressures) on the adoption of green innovation strategies. Producing and using organic products and processes and recycling activities are found to have a significant direct positive impact on business performance. Our results also confirm the moderating effect of channel structures: the benefits of green innovation in terms of business performance are larger when firms use more direct sales channels (selling wine directly from the wine cellar to consumers and businesses).  相似文献

ABSTRACT

Located in Southeast Asia as one of the most dynamic economic regions in the world and close to north-south shipping routes, Vietnam’s seaports play a vital role in promoting its international trade and economic growth. And yet, most ports are small and owned by the public sector. Their performance is subject to various factors relating to government policy, operational and market conditions. Although the Government has been trying to improve the sector’s performance through corporatization, its corporatization model is unique in many ways compared with reform models in other countries. This study seeks to analyse the effects of government policy, operational and market conditions among other factors, on Vietnamese seaports’ efficiency. Double-bootstrap data envelopment analysis (DEA) and univariate and multivariate analyses were conducted using the data sample of 41 ports for years 2015 and 2016. The analysis results show that the factors of production, regional location and reform policy had a significant impact on port performance.  相似文献

This paper provides a meta-analysis of studies on the effect of ownership on the performance of Russian firms over 20 years of rapid institutional and economic changes. We review 29 studies extracted from the EconLit and Web of Science databases with a total of 877 relevant estimates. We find that the government negatively affects company performance regardless of its administrative level. In contrast, private ownership is positively associated with firm performance. However, the effect size and statistical significance are notably varied among different types of private ownership. While the effect of insider (employee and management) ownership is comparable to that of foreign investors, the effect of domestic outsider investors is considerably smaller. Our assessment of publication selection bias reveals that the existing literature does not contain genuine evidence for a series of ownership types and, therefore, some of the findings have certain limitations.  相似文献

This article estimates monetary policy rules for two key emerging market economies: Brazil and China. It analyses whether the monetary authority reacts to changes in economic activity, financial markets, monetary conditions, the foreign exchange market and the commodity price. We assess the importance of nonlinearity using a smooth transition regression (STR) model. Using quarterly data over the time period 1990:1 to 2008:4, we find that considerations about the output gap and the real effective exchange rate (in the case of Brazil), and the inflation rate (for China) explain the nonlinear adjustment of the central bank rate. Moreover, the results suggest that central banks pursue a target range for the threshold variable rather than a specific point target. In the case of China, the McCallum rule shows that the GDP growth, the interest rate and the commodity price drive the response of the growth rate of the relevant monetary aggregate.  相似文献

This paper explores the role of technological opportunity and cumulativeness in the evolution of technological specialization patterns (TSP) in catching-up processes. Concretely, I assume that opportunity induces mobility while cumulativeness leads to diversification and stability. The empirical analysis uses patent data indicators for nine Asian and Latin American countries between 1978 and 2012. The paper shows that, during economic liberalization (although with different timings), emerging countries caught up and redefined the path of technological accumulation for Asian and Latin American countries. With the exception of Hong Kong, all the countries increased their technology share, but they ran in different directions. Asian countries made greater relative efforts in dynamic technologies, while Latin American countries focused on stagnant technologies. In this sense, Asian countries achieved a more successful performance, building new technological bases and taking a technological leap in some of the more dynamic technologies. Meanwhile, Latin American countries left their technological bases unchanged. The paper also shows that, at the beginning of the catching-up cycle, the TSPs were turbulent. Afterwards, cumulativeness in the technological choice induced the diversification and stabilization of the TSPs.  相似文献

By introducing uncertainty, monetary volatility and economic volatility are said to make the public cautious, hence increase their cash holdings or their demand for money. On the other hand, because of monetary and economic uncertainty if the public seek safer assets than money, they may hold less cash. In the absence of any paper testing for the impact of economic and monetary uncertainty on the demand for money in emerging economies, this article fills the gap by considering the experiences of six Central and Eastern European emerging economies and four other emerging economies. We found that the impact is transitory in most countries. Moreover, money demand is found correctly specified and stable in most countries, suggesting that policy based on monetary targeting could still be effective despite significant output and monetary uncertainty.  相似文献
