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

This paper investigates the relation between the extent of diversification in firms and their performance at different life cycle stages. To illustrate the joint endogeneity of diversification and performance, we treat both the extent of diversification and firm performance as endogenous variables in a simultaneous equation system. Empirical results reveal that corporate diversification erodes firm value. Overall, firms in their growing stages experience a significant diversification discount; however, mature firms do not show such findings. Although unrelated diversification leads to trading at a discount in all growing and mature firms, conversely, related diversification exhibits an evident premium in mature firms. 相似文献

Abstract. Post-Keynesian monetary theory is of increasing interest to economists in the light of world-wide financial deregulation of financial markets. This paper offers an exposition of the main issues in this area, including an overview of the most divisive issue, that of interest rate determination, and hence, the slope of the money supply function. Post-Keynesian monetary theorists divide into two camps with respect to the determination of interest rates: the 'markup school'and the 'liquidity preference school'. It is argued in the paper that the post-Keynesian theory of the business cycle, which incorporates endogeneity of the money supply, requires a liquidity preference notion of interest rate determination. 相似文献

We develop an estimation procedure that generates consistent estimates of the technology parameters, long-run (persistent) and short-run (transient) technical inefficiencies and the marginal effects of their determinants for the stochastic frontier model developed by Colombi et al. (2014, Journal of Productivity Analysis 42, 123) and Kumbhakar et al. (2014, Journal of Productivity Analysis 41, 321). Our approach accounts for three sources of potential endogeneity: (i) unobserved heterogeneity; (ii) simultaneity of input use with both types of technical efficiency; (iii) potential correlation of the noise term with the regressors. Using this approach we examine the effect of direct payments and farm size on the persistent and transient technical efficiency of French crop farms before and after the European Union's Common Agricultural Policy decoupling reform of 2003. Our results show that subsidy payments per hectare of utilised agricultural land had a significant positive effect on persistent technical efficiency and a significant negative effect on transient technical efficiency during the period before decoupling. For the period after the reform, the effect of subsidies is found to be significantly negative for persistent technical efficiency and insignificant for transient technical efficiency. The overall effect of subsidies on technical efficiency is found to be negative in both periods, albeit substantially lower in the period after decoupling. The effect of farm size on technical efficiency is found to be significant only for the period prior to the reform: it reduced persistent technical inefficiency but increased transient technical inefficiency during that period. 相似文献

The aim of this paper is to analyse the sensitivity of the natural rate of growth to the actual rate of growth for a sample of 11 Latin‐American countries, assuming the natural rate to be determined endogenously by changes in the actual rate of growth. The natural rates of growth are estimated in a system of SUR estimations over the period 1986–2003. In order to determine whether they react endogenously to changes in the actual rate of growth, a dummy variable for boom periods is added to the system of regressions. The results confirm the hypothesis about the endogeneity of the natural rate of growth. 相似文献

In this paper we present an alternative framework to neoclassical theory of international trade and exchange rate determination. Our model, inspired in the classical tradition, provides support for the assertion that an exchange rate policy aiming to improve national competitiveness and to bring about a sustained trade surplus is a viable option. In fact, the success of this strategy does not depend on the effectiveness of monetary sterilization —as many argentinean heterodox authors claim— but on the ability to overcome the boundaries imposed by the evolution of the domestic wage rate and the potential emergence of competitive devaluations. In the particular case of Argentina, the introduction of export taxes on land-intensive commodities, in which the economy has absolute advantages, brings an additional policy tool that can make both the exchange rate target and the workers claims consistent. 相似文献
