This paper examines the long-run effect of the level of foreign direct investment (FDI) on the level of total factor productivity (TFP) for 49 developing countries for the period 1981–2011 using panel cointegration and causality techniques. It is found that (i) FDI has, on average, a negative long-run effect on TFP in developing countries, (ii) long-run causality runs in only one direction, from FDI to TFP, (iii) in the short run, TFP has a negative effect on FDI, and (iv) the long-run effect of FDI of TFP differs between selected groups of countries: While the estimated long-run FDI–TFP coefficients are always relatively large, negative, and significant for countries with lower levels of human capital, financial development, and trade openness, the estimated effects are relatively small, insignificant, or even significantly positive for subgroups of countries with higher levels of human capital, financial development, and trade openness.  相似文献

Irrigation water rights and their governance structures constitute the foundation of local water institutions and profoundly influence water resource allocations, irrigated agricultural productivity and other consumptive water uses in the arid climate zones. This article explores the regional structures of irrigation water rights and water governance and empirically analyses the priority effects of water rights on irrigated agriculture at the micro level in Idaho, an arid and semiarid state in the western United States. We integrate a unique data set of water rights and water supplies with agricultural features and environmental characteristics into our empirical analysis. Results indicate that seniority in water resources allocation has significant, positive effects on both the average crop revenue and crop water use efficiency. Local water rights structures differ significantly in seniority and water sources from region to region. In response to the heterogeneity in local water rights structures, the aforementioned effect of allocative priority of water rights on average crop revenue per hectare and crop water productivity varies significantly, reaching up to an 87% difference, when measured across regions. In addition, the priority effects of water rights are nonlinear, which reflects the influence of historical patterns of water rights establishment on water institutions to date.  相似文献

The IMP (Industrial Marketing and Purchasing) Group has engaged in a number of interesting developments in the past few years. Particularly adventurous have been the agendas of ‘pictures’ and sense-making and of time. In this paper we argue that borrowing and combining contemporary foci within social science on narratives, identity, culture and epoché temporality (for which we use the acronym N.I.C.E) allows the construction of an approach that can integrate these IMP agendas into a new research direction for the group that will keep it at the leading edge of marketing research. The purpose of our paper is to introduce and integrate discursive and temporal elements into the understanding and research of business networks to develop a more dynamic and hermeneutic approach. Our purpose is to provide a contribution to the field in exploring how identities are formed within business networks through narrative episodes in interconnecting relationships over time. We bring together all of the elements of a NICE agenda in an attempt to provide an integrative, ‘multi-lens’ theory of business networks focussed within the IMP research tradition. In doing so, we construct meaning as itself networked; sense-making involves relating presently narrated episodes to symbolic and material aspects of other narrative network episodes and events through emplotment and storying.  相似文献

Forward guidance can be provided as an unconditional promise, i.e. commitment to a specific low policy rate. Alternatively, the promise may include an escape clause, i.e. a condition defining the state of the economy under which the central bank would not keep such a low rate and, instead, it would revert to setting policy under discretion. The escape clause can be expressed as a threshold in terms of a specific variable. The present paper shows that, when such a threshold is expressed in terms of an endogenous variable (e.g. output, inflation), there are cases where it becomes impossible for the central bank to act in a way that is consistent with its promise. Consistency imposes limits on the policy rate that can be set since reverting immediately to the optimal discretionary rate can be incompatible with exceeding the threshold.  相似文献

The Agri-Environment Footprint Index (AFI) has been developed as a generic methodology to assess changes in the overall environmental impacts from agriculture at the farm level and to assist in the evaluation of European agri-environmental schemes (AES). The methodology is based on multi-criteria analysis (MCA) and involves stakeholder participation to provide a locally customised evaluation based on weighted environmental indicators. The methodology was subjected to a feasibility assessment in a series of case studies across the EU. The AFI approach was able to measure significant differences in environmental status between farms that participated in an AES and non-participants. Wider environmental concerns, beyond the scheme objectives, were also considered in some case studies and the benefits for identification of unintentional (and often beneficial) impacts of AESs are presented. The participatory approach to AES evaluation proved efficient in different environments and administrative contexts. The approach proved to be appropriate for environmental evaluation of complex agri-environment systems and can complement any evaluation conducted under the Common Monitoring and Evaluation Framework. The applicability of the AFI in routine monitoring of AES impacts and in providing feedback to improve policy design is discussed.  相似文献

A total of 289 studies of returns to agricultural R&D were compiled and these provide 1821 estimates of rates of return. After removing statistical outliers and incomplete observations, across the remaining 1128 observations the estimated annual rates of return averaged 65 per cent overall — 80 per cent for research only, 80 per cent for extension only, and 47 per cent for research and extension combined. These averages reveal little meaningful information from a large body of literature, which provides rate-of-return estimates that are often not directly comparable. This study was aimed at trying to account for the differences. Several features of the methods used by research evaluators matter, in particular assumptions about lag lengths and the nature of the research-induced supply shift.  相似文献

An important adjunct of apartheid has been the absence of credible and comprehensive data on which policies, such as poverty reduction strategies, can be grounded. The 1993 Project for Statistics on Living Standards and Development (PSLSD) provided the first comprehensive household database for South Africa. Despite its usefulness, however, the one round PSLSD cannot provide answers to many questions important to policy researchers and practitioners, particularly questions about dynamic processes. The primary objective in this article is to introduce a new longitudinal household database, based on the PSLSD, which begins to fill this gap. Households surveyed by the PSLSD in KwaZulu-Natal province were re-surveyed in 1998 by the KwaZulu-Natal Income Dynamics Survey (KIDS). As a research endeavour, the KIDS project addresses one of the most vexing and important problems confronting contemporary South Africa: understanding the forces and mechanisms which contribute to the perpetuation of apartheid's legacy of poverty and inequality.  相似文献

Interconnection in Network Industries   总被引:4,自引:0,他引:4  
Recent deregulation of telecommunications in the U.S. and elsewhere has highlighted the importance of interconnection in network industries. In this paper, we analyse interconnection in a deregulated network where the participants compete in the final retail market. We consider both the case of a mature industry as well as one where a new entrant challenges the incumbent. In the later case, network externalities allow the incumbent to use the terms of interconnection to maintain its dominant position. Moreover, in either case, competition in the retail market can be undermined by collusion over access prices. We discuss the implications for some of the provisions of the new U.S. Telecommunications Act, specifically mandatory interconnection and reciprocity of tariffs, comparing these to the simple bill and keep rule.  相似文献
