National investment in technological activity is commonly justifiedin terms of the positive impacts upon productivity, internationalcompetitiveness and related aspects of national economic performance.This premise has found a supportive theoretical framework inthe new technology and growth models. Based on extended technology-gapmodels, this study examines cross-country empirical evidenceon the relationship between technology-intensive trade performance(as a proxy for technological output) and per capita economicperformance, utilising 1978 to 1992 data for around 45 nations.The results provide some support for a positive relationshipbetween trade performance and economic returns. However, theweak and often inconsistent results suggest that the unconditionalpursuit of technology-intensive trade improvements may not necessarilyhave the expected net benefits.  相似文献

This paper outlines a new technique, which makes optimal control in a stochastic minimum variance framework computationally feasible. The new approach is then used to evaluate gains to policy coordination in the context of a macroeconometric model for the G-3. More specifically, we consider policy responses to a temporary price shock in a single country and in multi-country cases. The results show that coordination brings about a striking improvement in the overall control of inflation and a reduction in output costs.  相似文献

This study provides an empirical analysis of the market for some male prostitution services in the UK. Flexible working hours, part-time working, and multiple job holding are considered as important labour market characteristics in this service sector. Statistical models helping explain the provision of a deviant and a more mainstream sexual service is reported, utilizing cross-section data drawn from individual prostitute advertisements. The significance of various declared intrinsic endowments of the prostitutes are examined in relation to the offer of these services, including age, ethnicity, physique, and masculine demeanour.  相似文献

The relationship between the number of road accidents and the volume of traffic is econometrically estimated in this paper. A stratified random sample of 399 road segments covering urban and rural roads in New York State(USA) in 1985 is analysed. No significant externality is detected. On ver high volume urban roads the marginal to average accident rate ratio is 1.06. On all other roads, a ratio of 0.98 is estimated. These findings contrast sharply with those of Vickrey, who estimated a ratio of 1.5 for California freeways in 1962. The results are, however, consistent with the ‘official view’ of both the US and UK highway authorities that no significant accident externality exists.  相似文献

A link between unionization and research and development rates (research and development expenditures divided by output) is tested for in thirteen aggregate Canadian industries. A balanced panel of thirteen industries covering 1968 to 1986 reveals a negative relationship between industry unionization rates and research and development. The results hold when a number of techniques are used to control for unobserved industry heterogeneity and non-linear responses to unionization. In an industry that moves from the 25th to the 75th percentile of unionization, research and development is predicted to fall by about 40 per cent. JEL Classification: J51
Les effets des syndicats sur l'intensité de la recherche et développement: une analyse empirique sur plusieurs années . Ce mémoire examine le lien entre le degré de syndicalisation et les taux de dépenses en recherche et développement en proportion de la production dans treize industries canadiennes. Pour ces treize secteurs industriels, entre 1968 et 1986, il semble qu'il y ait une relation négative entre les taux de syndicalisation et les taux de dépenses en recherche et développement. Ces résultats sont robustesmême quand on utilise des techniques pour tenir compte de l'hétérogéneité des secteurs et des réponses non linéaires à la syndicalisation. Pour une industrie qui voit son taux de syndicalisation passer du 25e au 75e percentile, on prévoit une chute de 40% dans la recherche et développement.  相似文献

This paper examines factors determining airport charges. Using data for 100 large airports in Europe, we find that they charge higher prices when they move more passengers. Additionally, competition from other transport modes and nearby airports imposes some discipline on the pricing behavior of airports. Low-cost carriers and airlines with a high market share seem to have a stronger countervailing power. We also find that private airports not regulated charge higher prices than public or regulated airports. Finally, the regulation mechanism does not seem to influence substantially the level of airport charges.  相似文献

This paper explores the role of the financial system in technological catching-up in the expectation that financing mechanisms affect the production and the exports of new or “new to the market” commodities. We have developed indices of related export variety (REV) and of unrelated export variety (UEV) by using the informational entropy function for a sample of 97 countries using NBER & UN trade data for the period 1992–2005. We used these indices sequentially as dependent variables with the bank credit ratio and stock market capitalization ratio as independent variables. In addition, we include the education system, natural resources and four principal component factors characterizing the cost of doing business, political system, quality of governance and the degree of openness of the countries as control variables in our regressions. Our pooled regression models show that the financial system is an important determinant of both types of export variety for all countries but that, for the most successful developers, the banking system and the stock market play different roles, with the former being relatively more appropriate for REV and the latter for UEV. Such specialization of different forms of the financial system seems to confirm that stock markets are likely to be relatively more appropriate to fund the exploratory type of innovations which are required to increase UEV.  相似文献

Recent studies have analysed the impact of capital account opening on income growth, implicitly assuming that the various forms of foreign savings have similar effects. In fact, theoretical considerations suggest that the individual components of private capital inflows have different effects on growth. This paper analyses the link between income growth and private capital inflows. It presents system GMM estimates with annual observations from 1985 to 1996 for 72 countries. When full-sample results are checked for country and period changes, most of capital inflow series lose their ability to explain income growth. Bank flows stand as the sole source of foreign financing that displays a positive and robust correlation with growth.  相似文献

In examining China's exchange rate policy in the reforming years, the study finds empirical evidence of its long-run inflationary consequences, but the effects appear not to be sizable. In the short run, while changes in the devaluation rate are positively correlated with the increase in the growth rate of inflation, the inflation inertia is also modest. The moderate inflationary cost of devaluations provides some explanation of the smooth transition of exchange rate policy regime in China and the authorities' ability to put more weight on external competitiveness.  相似文献

Sudden stops and their negative effects on GDP have recently received increased attention because quantitative easing has led to substantial capital inflows into emerging economies. We extend the empirical literature on the impact of sudden stops on GDP by proposing an alternative econometric approach which is multivariate, nonlinear and uses a novel way to identify sudden stops. We estimate a Markov switching vector autoregression with a latent variable indicating whether the economy is in a sudden stop regime. We use the maximum fraction of forecast error variance approach for partial structural identification of the vector autoregression model. Beyond confirming findings from the existing empirical literature on sudden stops, our results additionally show that (i) sudden stops are associated with regime switches (i.e., breaks in the behavior of economic variables), which have significantly negative and permanent effects on GDP; (ii) impulse responses to net capital inflow shocks are regime dependent with economies being more vulnerable to shocks during the sudden stop regime; and (iii) there were different main drivers of the output decline in historical sudden stop episodes.  相似文献

This paper examines consumption patterns of urban households in China using aggregated household consumption data. A demand system comprising six commodities (rice,pork,vegetables,fish,eggs and fruits) is estimated using a two-stage budgeting procedure which incorporates an almost ideal deamnd system (AIDS) in each stage, Elasticity estimates from the system are plausible and consistent with other relevant studies. Results from this study strengthen the evidence of the emergence of a large Chinese market for non-stable food. The study provides rationale and basis for additional research into Chinese food consumption, especially processed food.  相似文献

The spur for privatization and its impact on economic performance have been analysed from many perspectives, including microeconomics, macroeconomics, and institutional economics. Previous research has focused on efficiency reasons for privatization at the level of the firm, and the relative performance of state‐owned enterprises and privately owned firms. This article investigates the macroeconomic facet of privatization with particular attention paid to the relation between privatization and capital formation in developing countries. Our study uses recent World Bank data on privatization for 105 countries over the time period 1988–2003. We explore the impact of privatization on capital formation by conducting two‐stage least squares and ordinary least squares estimations within three time frames. Our findings indicate that the effect of privatization on capital formation varies across regions and time frames. In general, privatization is neutral with regard to investment.  相似文献

Variables suggested by theoretical studies of indexation are considered with a view to examining their utility in the context of the decision to index (incidence) and the desired degree of indexation when escalator clauses are put into effect (intensity). The Tobit model, which can address both of these issues, suggests that most of the effects of explanatory variables on the regressand occur by modifying the incidence of indexation, not its intensity. However, the Tobit model is itself rejected in favour of separate Probit and Truncated Regression investigations of incidence and intensity, respectively. The results obtained indicate that the standard list of explanatory variables, which one thinks of in the context of the theoretical literature as dealing primarily with intensity, perform well in explaining incidence but very poorly in accounting for the non-limit observations. The latter are influenced by bargaining power proxies such as the unemployment rate and union density; a very clear trade-off between indexed and non-contingent wage adjustment can also be discerned. These results call for more theoretical attention to the distinction between indexation incidence and its intensity.  相似文献

This study employs recent advances in time-series analysis, cointegration and error correction model, to examine the long-run and short-run determinants of the exports and trade imbalance between the USA, Japan, and Taiwan. The unit root tests reveal nonstationary in most of the variables. The cointegration tests affirm positive the long-run associations are between the exchange rate changes and the exports as well as the trade imbalance. Once these long-run effects are accounted for, it is found that there are evidences of short-run relationship between these variables.  相似文献

Abstract.  We investigate the impact of international outsourcing on productivity using plant-level data for Irish manufacturing. Specifically, we distinguish the effect of outsourcing of materials from services inputs. Moreover, we examine whether the impact on productivity is different for plants being more embedded in international markets through exporting or being part of a multinational. Our results show robust evidence for positive effects from outsourcing of services inputs for exporters, either domestic or foreign owned. By contrast, we find no statistically significant evidence of an impact of international outsourcing of services on productivity for firms not operating on the export market.  相似文献

This study tests to what degree the incidence of payroll taxes in Germany is on employment and whether in consequence payroll taxes, in particular social insurance contributions, are the culprit behind the growing unemployment problem. Using industry level data for 18 years (1977–1994) a system of five dynamic factor demand equations is estimated. Various simulations indicate that the employment effects of payroll taxes are minimal.  相似文献

The functioning of labour markets from a demand-side perspective is examined. In particular, the determinants of vacancy duration are studied in the context of a model of employers' search behaviour. A model for the choice of the recruitment strategy at the start of the search process and the corresponding recruitment duration is developed in which allowance is made for different patterns of duration dependence for each recruitment strategy. This model is applied to data on employers' search behaviour in the Dutch labour market. It is found that employers prefer advertisements as the first recruitment channel when applicants are required to have work experience. Moreover, employers prefer to start searching via the labour exchange office when jobs in the secondary segment of the labour market have to be filled. It is also found that - when advertisements are used as the first recruitment strategy - employers need some time to acquire a pool of applicants and to select candidates from this pool. It is interesting as a contrast that applicants seem to be evaluated rather quickly if employers start searching via informal contacts.  相似文献

This paper examines the long-run relationship between UK aggregate imports and the macroeconomic components of final expenditure, using the Johansen multivariate cointegration analysis. It is found that there are significant differences between the long-run elasticities of import demand with respect to the different components of final expenditure, over the period 1972 to 1990. An error correction model is proposed for short-run forecasting of UK aggregate imports. The short-run model appears to track the data well.  相似文献

This article explores the hypothesis that state administrativeagencies spend more time and effort attempting to protect theiractions from judicial review in states with more independentappointed courts (as opposed to less independent elected courts).This is because more independent courts are (by definition)less influenced by the political/electoral forces that underlieagency - policymaking - as rational actors, agencies may thereforebe expected to recognize the degree of judicial independenceand respond to it. Three state agencies subject to substantialjudicial review in the 1970s are examined: utility commissions,insurance commissions, and the public education bureaucracy.Controlling for relevant political factors, each is found tohave significantly larger staffing for a given regulatory workloadin states with more independent appointed courts, consistentwith the hypothesis.  相似文献

ABSTRACT

Almost all empirical research that has attempted to assess the validity of the Porter hypothesis (PH) has started from reduced-form models, for example, single-equation models for estimating the contribution of environmental regulation to productivity. This paper follows a structural approach that allows testing what is known in the literature as the ‘weak’ and the ‘strong’ version of the PH. Our ‘Green Innovation’ model includes three types of eco-investments to explain differences in the incidence of two types of eco-innovation, which are allowed to affect labor productivity. We allow for complementarity between the two types of eco-innovations. Using a comprehensive panel of Dutch manufacturing firm-level data we estimate the relative importance of environmental regulations on eco-investment and eco-innovations. The results of our analysis show a strong corroboration of the weak and a nuanced corroboration of the strong version of the PH.  相似文献
