We investigate the impact of direct payments on agricultural commercialisation in Kosovo. Kosovo is one of the poorest countries in Europe but, with European assistance, provides substantial funds to support agriculture, made up of many small and often semi‐subsistence farms. Thus, the effect of this support is a central policy issue. Identifying the effect of direct payments on market participation faces endogeneity issues arising from the possible simultaneous determination of participation in support programmes and market participation. In order to achieve proper identification of the endogenous direct payments, we use a strategy of targeted identification search that employs several different methodological approaches. We find that direct payments for fruit and vegetables, and those for cereals and oilseeds have a positive effect on market participation. However, we cannot identify any definite effect of livestock payments.  相似文献

We examine the effects of two different types of commodity taxation, specific and ad valorem, on wages and profits. We analyze two models of wage determination, one with efficiency wage setting and one with union-firm bargaining. In the former, a (locally) revenue-neutral shift from specific to ad valorem taxation leads to an increase in both employment and wages and a reduction in profitability. In the latter, the effect on wages and profits may be reversed: predominantly ad valorem taxation raises employment but lowers wages, and under certain circumstances, the net effect is an increase in profits.  相似文献

This paper analyzes the effect of lifting primary school fees on educational attainment in Uganda. After the abolishment of school fees in 1997, the enrollment rate more than doubled. Two decades later, we know little about the effect of the policy on educational attainment. With recent data on eight cohorts exposed to free education, we analyze the impact of the policy on years of completed primary school, completion of primary school, and transitioning to secondary school. We use a straightforward regression analysis with cohort dummies and household fixed effects to control for unobserved heterogeneity. We find that lifting school fees had no effect on the years of primary school achievement and the likelihood of primary school completion. We find some weak evidence that the likelihood of those who completed primary education to start secondary school increased after Universal Primary Education.  相似文献

We provide a new framework for estimating the systematic and idiosyncratic jump tail risks in financial asset prices. Our estimates are based on in-fill asymptotics for directly identifying the jumps, together with Extreme Value Theory (EVT) approximations and methods-of-moments for assessing the tail decay parameters and tail dependencies. On implementing the procedures with a panel of intraday prices for a large cross-section of individual stocks and the S&P 500 market portfolio, we find that the distributions of the systematic and idiosyncratic jumps are both generally heavy-tailed and close to symmetric, and show how the jump tail dependencies deduced from the high-frequency data together with the day-to-day variation in the diffusive volatility account for the “extreme” joint dependencies observed at the daily level.  相似文献

This is an empirical study on the growth impact of Information and Communication Technologies using industry-level data for the US and the EU industries over the period 1980-2000. A panel data approach is employed to estimate the ICT effect using the system GMM and the pooled mean group panel data estimators. The results vary depending on the period, the region, and the type of industry considered. The GMM estimates suggest a significant ICT effect on growth during the 90s both in the US and in the EU. This effect for the EU was strong in the early 90s and weakened afterwards, as opposed to the US where it strengthened in the late 90s. The results of the pooled mean group estimator confirm that the long run growth contribution of ICT was significantly positive in the industries of both regions and over the entire period 1980-2000. However, it seems that the productivity effects of ICT are mainly present in the industries which are either ICT producers or heavy ICT users.  相似文献

This paper investigates how particular configurations of institutional conditions cause high rate of long-term unemployment and non-standard employment rate for 18 OECD countries during the period of 2001–2008. The paper aims to investigate how employment protection legislation (EPL), unemployment benefit and statutory minimum wages are associated with long-term unemployment and non-standard employment. Using the fuzzy-set analysis, the paper examines how the combination of policies matters in causing long-term unemployment and/or non-standard employment. The result suggests that a low level of statutory minimum wage can lead to high levels of non-standard employment in combination with either strict EPL for permanent workers or weak EPLs for temporary workers. The long-term unemployment rate is suggested to be high when there is strict EPL for temporary workers in combination with high levels of statutory minimum wage. This paper highlights the importance of examining multiple policies as configuration.  相似文献

We examine the determinants and outcomes of Chief Executive Officers (CEOs) accepting a $1 salary, a compensation practice that occurs relatively frequently in high‐profile firms and is debated by regulators, investors, and the media. Using a hand‐collected sample of 93 CEOs from 91 firms between 1993 and 2011, we examine the triggers preceding the $1 salary decision, the factors associated with the decision, subsequent stock returns, and the outcomes for the CEOs. Our evidence is consistent with two explanations for the phenomenon: (i) it is a gesture of sacrifice by CEOs of firms in crisis, and (ii) it is a signal of better future performance by CEOs of growing firms. Our analyses highlight the two different circumstances and shed light on an interesting debate that has thus far been supported only by anecdotal evidence.  相似文献

The increasing globalization of economies and the concurrent increase in the risk of currency exposure has stimulated the development of new instruments to allow both investors and traders to hedge their currency risk. The expansion of these derivatives, however, has raised some concerns. This paper studies the determinants of the dynamics of exchange rate future contracts as a means to identify the sources of such concerns. By using a mean-exponential generalized autoregressive conditional heteroskedasticity (M-EGARCH) model for five different future contract lengths and six developed economies, it is found that an M-EGARCH(1,1) effectively describes the exchange rate futures' daily dynamic. Sign, size, and persistence effects on the volatility of future contracts are all significant, thus providing important information to both policy makers and market participants.  相似文献

Social influence on consumer behavior has long been a subject of academic research in various scientific fields. According to research by Salganik, Dodds, and Watts (2006), music demand is a function of social influence between consumers. Market concentration tends to increase when information on demand becomes publicly available. In addition, stochastic agglomeration caused by social influence decreases the predictability of market success. These heavily cited findings challenge traditional market research and provide important insights on the impact of social media and sales charts. We test the stability of their results by replicating the study on music demand in a slightly different setting. We further investigate the generalizability of findings by probing other product categories and different phases of purchase decisions, i.e., interest, consideration, and actual demand. Across all categories and across all dependent variables, we are able to replicate the direction of the effects. We do, however, consistently obtain smaller effect sizes than reported in the original paper.  相似文献
