Our study contributes to the search for the elusive catalytic effect of International Monetary Fund (IMF) lending on inflows of foreign direct investment (FDI). Recent scholarship has found that the catalytic effect is conditional on political regime and program stringency. We contribute to this literature by developing and testing a theory which describes how the catalytic effect also varies by economic sector. This is a departure from existing studies, which have tended to focus on aggregate FDI flows after crises. Our findings corroborate previous research, which finds that in general IMF lending has a substantial and negative effect on FDI. However, we find that the negative effect is concentrated in sectors that are highly dependent on external capital and have low sunk costs in the host country. Our findings are robust to several alternative explanations common in IMF literature, namely the importance of IMF program design and the ability of governments to make credible commitments to reform. Substantively, our findings suggest that investors are more likely to use IMF lending as an escape hatch in countries where FDI is dependent on external capital and has low sunk costs.  相似文献

This analysis charts the changes in British aid policy under the Margaret Thatcher government (1979–1990). In particular, it examines the impact of so-called neo-liberal ideology in overseas development strategy in an era where “structural adjustment”—aid in return for market-based reforms—became World Bank and International Monetary Fund orthodoxy. There is some evidence to show British increases in multilateral aid during the 1980s supported a neo-liberal aid policy. Bilateral aid policy, however, demonstrated a subordination of aid to foreign policy and a pro-business—not ideologically pro-market or neo-liberal—alignment. One of the results of these structural changes was the Pergau Dam scandal at the end of the Thatcher years.  相似文献

Abstract

Now marketed as a tropical beach destination, Okinawa's identity is also forever linked with the horrors of war. Okinawa's tumultuous past encompasses the Ryukyu Islands, which had close economic ties to China until being annexed by mainland Japan, were invaded by the US in the Second World War, were occupied until 1972 and, more recently, have become the centre of heated debates over the continued presence of US military bases. The Battle of Okinawa was one of the bloodiest of the Second World War and the inhabitants faced not only the American invasion but also the tactics of the Japanese army, who viewed the islands as expendable in order to slow invading forces from reaching mainland Japan. In the context of the seventieth anniversary of the end of the Battle of Okinawa in 2015, and beyond, it is argued here that these conflicting geopolitical disputes present significant challenges in terms of the messages presented to educational dark tourists visiting the Okinawa Peace Park and Memorials. The Peace Park Story Tellers or kataribe who are the Second World War survivors, have the critical task of mediating the message to both domestic and international tourists, some of whom are not prepared to hear anti-Japan sentiment. Through an examination of the historical and geographic background, and an analysis of the tourist experience at the Peace Park and Memorials, this paper explores the complexity of educational dark tourism where competing messages collide.  相似文献

This article analyses welfare impacts of fertiliser adoption using data collected from 838 cocoa farm households in the four key cocoa-producing regions in Ghana. Using propensity score matching (PSM), the study indicates that application of fertiliser leads to significant gains in farm yields, farm income, consumption expenditure, consumption expenditure per capita, and value of productive farm assets. The article concludes that cocoa-specific programmes such as Cocoa High Technology (Cocoa Hi-tech), initiated to intensify the application of improved farm technologies such as fertiliser, should be strengthened through effective and efficient management systems.  相似文献

Research on the health benefits and consequences of close relationships has suggested the linkage in daily emotions (i.e., coregulation) between close partners is an important relationship dynamic. While the coupling of daily emotions among family members (parent–child and marital dyads) has been widely documented, research examining emotional coregulation among ethnic minority youth during adolescence, a period marked by heightened emotion and risk for psychopathology, remains an important area in need of exploration. This study examined correlates of emotional coregulation in a sample of Mexican-origin adolescents (Mage?=?15.02, SD?=?.83) and their parents (Mage?=?41.93, SD?=?6.70). Dyads reported on daily levels of distress and happiness for 14 consecutive days across two waves of data collection a year apart (nwave1?=?428 dyads, nwave2?=?336 dyads). Dyads who reported getting along were more likely to coregulate their daily happiness. Importantly, coregulation of distress was only present in older adolescents who reported above average levels of internalizing symptoms. The results suggest coregulation of distress may shape or be shaped by poor mental health during the later years of adolescence, a time when youth may be establishing a degree of emotional autonomy from parents.

This article demonstrates that World Bank internal learning has led to significant changes in how the organization interacts with government officials through survey missions. Reviewing evidence of institutional learning and associated changes in practice and focusing on the relational modes being manifest in technical assistance, the article identifies three main phases of World Bank survey missions: general survey missions (1940s–1960s), country assistance strategies (1990s–2000s), and country partnership frameworks (2010s). Overall, World Bank reviews have repeatedly highlighted the importance of non-hierarchical interactions between Bank staff and country officials. In recent years, practice has begun to catch up with these operational insights.  相似文献

This article argues that the sources of official and societal ambivalence towards civic nationhood in today’s Russia are found in the institutional instability and personalist dynamics of hybrid regime politics in the 1990s. Successful civic nation-building should institutionalize inclusive criteria for citizenship as a basis for policymaking, which in turn should create incentives for dominant ethnicities to embrace civic nationhood. While the shifting views of Boris Yel’tsin on nationalities policy and the constant turmoil in the government’s nationalities ministry have received little scholarly attention, they illuminate the endogenous sources of regime instability in relation to civic nation-building. Russia’s experience thus challenges the traditional view of ethnic nationalism as fostering authoritarianism and civic nationalism as fostering democracy: rather, competitive authoritarianism in the 1990s confounded the regime’s own efforts toward civic nation-building and laid the groundwork for the “ethnic turn” in Russian politics under Vladimir Putin.  相似文献

This study used data from a sample of 6th to 12th grade students (N = 48,641, 51% female), nested in 192 schools, to determine if the influence of family-based protective factors varied across different school contexts. Hierarchical logistic regression models were used to examine the effects of individual-level family protective factors, relative to school-level aggregates of the same factors, on recent (past 30 days) use of cigarettes, alcohol, and marijuana. Cross-level interactions indicated that the effect of the student’s level of family protection, relative to other students in their school, differed depending on the aggregated school level of family protection. The results suggested that the benefit of belonging to a well-functioning family was more influential for students attending schools characterized by higher-than-average aggregated levels of protection compared to students attending schools of lower-than-average protection. Thus, family-level factors offered less protection for students in relatively high-risk school contexts. These results were consistent with a protective–reactive interaction and suggest that a thorough understanding of adolescent substance use must consider the complex interplay among adolescents, their families, and their social environments.  相似文献
