According to conventional wisdom, terms‐of‐trade shocks represent a major source of business cycles in emerging and poor countries. This view is largely based on the analysis of calibrated business‐cycle models. We argue that the view that emerges from empirical structural vector autoregression (SVAR) models is strikingly different. We estimate country‐specific SVARs using data from 38 countries and find that terms‐of‐trade shocks explain less than 10% of movements in aggregate activity. We then estimate key structural parameters of a three‐sector business‐cycle model country by country and find a disconnect between the importance assigned to terms‐of‐trade shocks by theoretical and SVAR models.  相似文献

RESUME : Cet article analyse les effets de la politique budgétaire sur l’investissement privé au Bénin à l’aide de deux modèles économétriques (l’approche par le flux d’investissement public et l’approche par le capital public), estimés en utilisant les outils d’économétrie avancée tels que les tests de racine unitaire et de cointégration et en appliquant la procédure en deux étapes suggérée par Engle et Granger (1987) . Nos résultats indiquent que la politique fiscale mais aussi le stock permanent de capital privé et le crédit au secteur privé favorise l’investissement privé. Cependant, la formation de capital public et les dépenses de consommation publique évincent l’investissement privé.  相似文献

Employment matters for development because it can raise household income, lower inequality, promote economic growth, and contribute to political stability. Many countries have high rates of public employment, but what effect does this have on overall employment and unemployment rates? This paper investigates if and to what extent public‐sector employment crowds out (reduces) private‐sector employment. In particular, we estimate regressions of unemployment or private‐sector employment on two measures of public‐sector employment. The study uses an especially assembled dataset, which is novel for its coverage of a large sample of developing countries as part of a panel of rich and poor countries. Our results point to full or just about full crowding‐out for the entire sample. Unlike previous cross‐country studies, which were restricted to advanced economies, we are able to show that these results also apply to developing countries, although crowding‐out may not be quite as high as in advanced economies. The results mean that high rates of public employment have an offsetting large negative impact on private employment rates and do not reduce overall unemployment rates. With the qualifier that government activities may help the economy in other ways, our results imply that, rather than creating public‐sector jobs, scarce fiscal resources could be better spent on other developmental needs.  相似文献

Previous studies of aid allocation have concluded that foreign aid is allocated not only according to development needs but also according to donor self‐interest. We revisit this topic and allow for donor‐ as well as recipient‐specific effects in our analysis. In addition to comments on the statistical significance of our results we assess the relative economic importance of recipient need, merit, and donor self‐interest. Our results indicate that all bilateral donors allocate aid according to their self‐interest and recipient need. However, most bilateral donors seem to place little importance on recipient merit. Less than 1% of the variance of aid is accounted for by merit, ceteris paribus. The UK and Japan are exceptions: they allocate more aid to countries with higher growth, higher democracy scores, and fewer human rights abuses.  相似文献

Based on the fact that not all farmers adopt a technology at the same time, it is argued in this paper that the distinction between groups is important because early, medium and late adopters respond differently to economic and non-economic factors when they consider whether to take up organic farming or not. The individual effects on adoption between the groups are identified by the use of multinomial logit analysis. The results provide evidence that there are significant differences in the characteristics between the adopter groups. The findings also reveal that the factors that affect adoption play a different role for early, medium and late adopters, particularly with regard to farming intensity, age, information gathering as well as attitudes of the farmer. More specifically, early adopters were the youngest to adopt organic farming and their decisions were found to be less profit related compared to other groups. Late adoption is constrained by risk considerations, while environmental attitudes and social learning were identified to be important determinants for all adopter groups. Overall, the findings strongly suggest, that for policy measures to be effective, the current state of diffusion has to be taken into account.  相似文献

In this paper, we propose an empirical model of Internet adoption which takes into account the household’s desire to adopt the Internet. Our research supports three central findings. First, we determine the main factors that explain the cross-sectional variance in gross benefits. Second, we estimate the predicted probabilities that a household does not desire to adopt the Internet and that a household desires to adopt the Internet but does not because its adoption costs are higher than its gross benefits. We show that while the cross-sectional variance in the first predicted probability is high, the cross-sectional variance in the second one is low (except for the age factor). Third, we compute the predicted adoption probability assuming that the adoption costs are homogeneous across households. We show that, for a given dimension (except for the age factor), the adoption rate will be only slightly modified if the adoption costs are homogeneous across households. Our results support the argument that the digital divide is mainly due to differences in gross benefits of adoption.  相似文献

Abstract We analyse a very rich and unique panel database that provides information on exports at the firm‐product level. Motivated by the recent theory of multi‐product firms, we investigate what determines the survival of products in the export mix to find that, in export dynamics, characteristics of the product as well as that of the firm matter. In particular, firm productivity as well as product scale and tenure are associated with a higher export survival rate. This suggests, in line with theory, that there are firm‐ as well as firm‐product‐specific competencies that are important for shaping firms’ export mix.  相似文献

Non‐Linear Oil Price Dynamics: A Tale of Heterogeneous Speculators?   总被引:1,自引:0,他引:1  
Abstract. While some of the recent surges in oil prices can be attributed to a robust global demand at a time of tight production capacities, commentators occasionally also blame the impact of speculators for part of the price pressure. We propose an empirical oil market model with heterogeneous speculators. Whereas trend-extrapolating chartists may tend to destabilize the market, fundamentalists exercise a stabilizing effect on the price dynamics. Using monthly data for West Texas Intermediate oil prices, our STR-GARCH estimates indicate that oil price cycles may indeed emerge due to the non-linear interplay between different trader types.  相似文献

We formulate a small and stylised dynamic macroeconomic model, and study how different specifications of the supply side affect the model's dynamic properties. The wage‐price equilibrium‐correction model (ECM) and the Phillips curve model (PCM) that both can be used to represent the supply side of a New Keynesian macro model, are synthesised in a generalised model of the wage‐price spiral. We show that the choice of ECM or PCM has implications for the long‐run stability of the macro model, without need of a NAIRU. We also find that the range of theoretically admissible dynamics is wide. For example, both the ECM and PCM may display endogenous cyclical fluctuations in inflation and unemployment, showing that even simple structures can give rise to complex dynamics. In practice that may entail that forecasting the effects of shocks and policy changes is difficult even in the best of circumstances.  相似文献

ABSTRACT: The European Commission has formally recognized that adequate provision of basic household services, including energy, communications, water and transport, is key to ensuring equity, social cohesion and solidarity. Yet little research has been done on the impact of the reform of these services in this regard. This article offers an innovative way to explore such questions by analyzing and contrasting stated and revealed preferences on citizen satisfaction with and expenditure on two services, telecommunications and electricity, in two large countries, Spain and the UK. We find evidence that in telecommunications, but not in electricity, reform has led to a ‘two‐track’ Europe, where citizens who are elderly, not working or the less‐educated behave differently in the market, with the result that they are less satisfied with these services than their younger, working, better‐educated, counterparts.  相似文献

Abstract .  South-South trade agreements are proliferating. Yet the impact of these agreements is largely unknown, as existing North-North and North-South micro-level studies are likely to yield misleading predictions for South-South trade agreements. This paper estimates the impact of COMESA on Uganda's imports between 1994 and 2003. Detailed import and tariff data at the 6-digit Harmonized System level are used for more than 1,000 commodities. Based on a difference-in-difference estimation strategy, the paper finds that – in contrast to evidence from aggregate statistics – COMESA's preferential tariff liberalization has not considerably increased Uganda's trade with member countries, on average, across sectors. The effect, however, is heterogeneous across sectors. Finally, the paper finds no evidence of trade-diversion effects.  相似文献

Abstract. During the last decade, many Western economies reformed their welfare systems with the aim of activating welfare recipients by increasing welfare‐to‐work programmes (WTWP) and job‐search enforcement. We evaluate the short‐term effects of three important German WTWP implemented after a major reform in January 2005 (‘Hartz IV’), namely short training, further training with a planned duration of up to three months and public workfare programmes (‘One‐Euro‐Jobs’). Our analysis is based on a combination of a large‐scale survey and administrative data that is rich with respect to individual, household, agency level and regional information. We use this richness of the data to base the econometric evaluation on a selection‐on‐observables approach. We find that short‐term training programmes, on average, increase their participants' employment perspectives. There is also considerable effect heterogeneity across different subgroups of participants that could be exploited to improve the allocation of welfare recipients to the specific programmes and thus increase overall programme effectiveness.  相似文献

We analyze the evolution of foreign direct investment (FDI) inflows to developing and emerging countries around financial crises. We empirically examine the Fire‐Sale FDI hypothesis and describe the pattern of FDI inflows surrounding financial crises. We also add a more granular detail about the types of financial crises and their potentially differential effects on FDI. We distinguish between mergers and acquisitions (M&A) and greenfield investment, as well as between horizontal (tariff jumping) and vertical (integrating production stages) FDI. We find that financial crises have a strong negative effect on inward FDI in our sample. Crises are also shown to reduce the value of horizontal and vertical FDI. We do not find empirical evidence of fire‐sale FDI; on the contrary, financial crises are shown to affect FDI flows and M&A activity negatively.  相似文献

Mobile payment becomes a convenient way to complete transactions due to the increasing popularity of mobile devices and the maturity of related technologies. Users’ experience of using computers and the Internet in financial activities largely affects their intention to use mobile payment. Combining the Technology Acceptance Model and Innovation Diffusion Theory, we examined the mediating effect of five factors, that is, perceived usefulness, perceived ease of use, compatibility, risk, and privacy concern, in the relationship between Internet experience and the adoption of mobile payment. Data from 922 mobile users supported the partial mediating effects of the five factors.  相似文献

The self‐employed face a tax‐induced disadvantage relative to wage and salary workers when it comes to the payment of health insurance premiums. This paper uses a panel of individual tax return data to test whether lower health insurance premium costs because of an expanded tax incentive result in longer periods of self‐employment. The results suggest that households claiming the deduction are indeed less likely to exit self‐employment. Equalizing the treatment of health insurance premiums for the self‐employed and wage workers by allowing full deductibility from Self‐Employment Contributions Act (SECA) taxes would result in a 7% decrease in the probability of exit.

We analyse empirically whether cooperatives and investor‐owned firms differ in terms of productive efficiency. Using rich Portuguese panel data covering a wide range of industries, we apply two different empirical approaches to estimate potential differences in productive efficiency. The results from our benchmark random‐effects model show that cooperatives are significantly less productive, on average, than investor‐owned firms, both at the aggregate level and for most of the industries considered. However, the results derived from a System‐GMM approach, which is our preferred empirical strategy, are much less conclusive, and we cannot conclude that cooperatives are generally less efficient that investor‐owned firms. With either approach, though, we find no evidence that cooperatives are more productive than investor‐owned firms in any industry.  相似文献

Growing reports indicate the presence of frauds in microfinance institutions (MFIs), as it can occur in any organization in countries where there are weak institutions, weak rule of law, and fraudulent behavior of MFI officers for personal gain. While there are increasing calls to launch financial governance of these NGO MFIs, there are concerns as to whether frauds of this nature can damage MFIs’ contributions to the credit market, particularly in the bank‐linkage program where the NGO MFIs act as third party intermediary. The purpose of this study was to analyze the collusion decisions faced by MFIs and their impact on the bank‐linkage program, which has been offered as a solution to help overcome adverse selection and moral hazard problems in the credit market by harnessing local information via MFIs. Our results show that even when there is a chance of collusion between MFI and the borrower, the linkage between MFI and bank can still increase the probability that the borrower puts in full effort, and therefore decreases the probabilities of both credit rationing and strategic default. Such linkage in financing viable projects can make micro‐financing more effective in achieving inclusive financial development and thereby poverty reduction in rural areas.  相似文献

The American Recovery and Reinvestment Act’s Broadband Technology Opportunities Program (BTOP) spent $4.7 billion during 2009–2013 to, inter alia, increase broadband adoption in underserved communities. We characterize the BTOP grants and examine the impact of the awards on broadband adoption. Econometric specifications controlling for award endogeneity related to observed and unobserved county-level factors find that spending is apparently associated with increased broadband adoption. Further investigation, however, reveals that the impacts of spending are nonlinear and even nonmonotonic over the range of county-level BTOP spending in the data. Controlling for trends to reduce the potential for spurious correlation between spending and outcomes removes most of the significance of the results. We conclude with three lessons for policymakers derived from the uncertain outcomes of BTOP spending found in our exploration.  相似文献
