Poland, one of the candidate countries for European Union membership, is currently experiencing acute structural problems within its agriculture sector. This article analyses technical efficiency and its determinants for a panel of individual farms in Poland specialized in crop and livestock production in 2000. Technical efficiency is estimated with stochastic frontier analysis (SFA) and confidence intervals are constructed. Determinants of inefficiency are also evaluated. The SFA results are compared with results using Data Envelopment Analysis (DEA). On average, livestock farms are more technically efficient than crop farms. For both specializations, the size–efficiency relationship is positive, that is large farms are more efficient. The SFA findings are generally supported by the DEA results. Soil quality and the degree of integration with downstream markets are highly important determinants of efficiency. The use of factor markets (land and labour) is important for crop farms, while livestock farms can rely on family labour and own land. Also, education is a constraint to efficiency particularly for crop farms. 相似文献

This paper examines how abundant global liquidity could influence the adjustment of banks’ leverage. Using banks in Hong Kong as an example, we find that the global liquidity effect is significant, and that mean reversion of banks’ leverage may under certain circumstances be more than offset by abundant global liquidity. Furthermore, we find that changes in global liquidity not only affect the level of leverage adjustment but also the adjustment speed of banks’ leverage. 相似文献

This article models the sequence of the effects of low tariffs in public river transport for goods. Within 10 years of deregulation, the public corporation had lost 83 per cent of its river traffic. The reasons for the inefficiency are made clear. The effects of low tariffs are examined, such as service rationing, overcharges, overcapacity and high budget claims, cost enhancement, and cross-subsidizing. The underlying objective is to formulate and apply an assessment method for transport policy that blends theories of rents and contestability in order to show how and why good intentions to boost demand by low tariffs in Zairian river transport produced very different results. Although illustrations are given for one mode of transport in one country, they are believed to be of much wider significance—to over 80 countries liberalizing their economies, including China, developing and east European countries. The National Transportation Authority (NTA, or Onatra) is a public corporation operating seaports, the Matadi–Kinshasa railway and an extensive network of river transportation 8,060 km long in the western half of Zaire. In the 1980s, it held monopolies on seaports and river ports, and shared the monopoly with the National Railway Authority (SNCZ) over the railways and the transport of mineral exports. The market in river transport appeared to be oligopolistic but it was dominated by the NTA. Since the NTA was one of the largest state-owned enterprises (SOEs), its experience is significant for many other SOEs and for the whole national economy. Ways to overcome inefficiencies are suggested, such as ending multiple public monopolies and cross-subsidies, privatization and deregulation. 相似文献

We find that managers with military experience pursue less tax avoidance than other managers and pay an estimated $1–$2 million more in corporate taxes per firm-year. These managers also undertake less aggressive tax planning strategies with smaller tax reserves and fewer tax havens. Although they leave tax money on the table, boards hiring these managers benefit from reductions in other gray areas in corporate reporting. The broad implications are as follows: for employee selection, boards can consider employees’ personal characteristics as a control mechanism when outputs are difficult to contract ex ante or measure ex post. 相似文献
