This paper considers the extent to which South African households have deleveraged, since the global financial crisis of 2007/2008. We extend the official South African Reserve Bank business cycle methodology to date financial cycles, from which we identify the peaks and troughs of the South African financial cycle going back to 1966. Our composite financial cycle index peaks in April 1974, January 1984 and May 2007; it has bottomed out in July 1979 and February 1999. Thus, we still await the trough. We further compare and contrast the deleveraging process in the current downward phase to the experiences from previous financial cycles. We find that the average period of the financial cycle in South Africa is much longer (approximately 17.3 years) than that of the business cycle (approximately 5.8 years), and that deleveraging has not yet matched the degree of deleveraging seen in previous downward phases. Our results suggest that further deleveraging is necessary, before we can expect to turn the financial corner. 相似文献

In this paper, we empirically investigate the effects of monetary policy shocks on exchange rates in Asian countries. To do so, we use VAR models which impose sign restrictions on impulse responses to identify monetary policy shocks. We find that contractionary monetary policy shocks lead to significant exchange rate appreciation in Malaysia, the People’s Republic of China, and the Republic of Korea. However, in India, Indonesia, the Philippines and Thailand, we find either a significant depreciation or no significant effect. These results suggest that an interest rate increase (or decrease) may not necessarily shield Asian countries from exchange rate depreciation (or appreciation) pressure following a U.S. interest rate increase (or decrease). 相似文献

We analyse the effect of a large scale infrastructure investment, namely the construction of the Oresund bridge, on the local and supra-regional economy. We employ the synthetic control method to construct counterfactual regions that mimic the trajectory of Malmo and Southern Sweden without treatment. Our results point to a positive effect. However, placebo tests in space and time only reveal statistical significance at a larger regional level. The results suggest that spillover effects are eminent. 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

This paper discusses the determinants of China’s outward foreign direct investment (OFDI) with a special focus on the role of government policy. In particular, we investigate the types of policies that are most influential in promoting OFDI. Our main contribution is to analyse, for the first time, China’s OFDI policies by means of quantitative indicators. We refine policies definitions and distinguish between Regulation Policies, Service Policies, Promotion Policies and Supervision Policies, and we develop a methodology for collecting, screening and coding policies; then we create new indices to capture different types of policies. We find that Regulation Policies, Service Policies and the general attitude of the government have significant effects on China’s OFDI at the national level. 相似文献

Share pledging for insiders’ personal bank loans is associated with the agency problems of insider risk aversion and stock price crash risk. We examine the relation between insider share pledging and the value of cash holdings using the pledging data of listed firms in Taiwan. We find that the value of cash holdings is lower for pledging firms, especially for those that are relatively more risk averse. Pledging firms that repurchase shares have a higher marginal value of cash than those with other payout methods, likely due to the role of repurchases in reducing the stock price crash risk. Our results show how insiders’ personal financing incentives arising from share pledging would affect the value of cash holdings from the perspective of agency problems and payout policy. 相似文献

I analyze the competition among different countries for ‘desirable’ and ‘undesirable’ potential immigrants, using both an immigration quota and a level of (imperfect) ‘scrutiny’ that would‐be immigrants face. Scrutiny imposes costs on immigrants and therefore makes it less attractive to immigrate. The number of applying undesirable immigrants increases in immigration quota and decreases in the level of scrutiny. In contrast, the number of desirable applicants can go in either direction as scrutiny increases and is independent of the immigration quota, because an increase in the immigration quota is completely crowded out by more applications by undesirable immigrants. 相似文献

[目的]分析评价江苏省现有农田保护经济补偿政策绩效与空间差异对建立完善长效的农业生态补偿机制和推动我国农业生态环境的可持续发展具有重要意义。[方法]以江苏省为研究区域,运用熵权-TOPSIS法,选取2010—2017年全省及苏北、苏中、苏南三个区域内11个指标,计算江苏省及三大区域农田保护经济补偿政策综合绩效值与经济、生态和社会效益单项绩效值,进行比较分析。[结果](1)江苏省农田保护经济补偿政策在2010—2017年8年综合绩效值由0189波动增长到0841,效果初现且具有较强推广价值。(2)经济效益绩效值以年均257%的增长率由0增长到1,效果最为显著,社会效益次之,生态效益自2013年后为绩效值中最低值,与前两项最大差距在05左右,反映出环境改善、农田质量提高效应远低于农户创收、社会公平效应,政策拟合度不高。(3)江苏省农田保护经济补偿政策效果存在空间差异,综合来看政策效果表现为苏南>苏中>苏北,苏南凭借经济优势在2016年和2017年的综合绩效值上比苏中苏北高出01、在经济与社会绩效值以002的差距领先且生态绩效值没有下降拐点,具有长效可持续性。[结论]现阶段农田保护经济补偿政策效果依赖地方政府经济实力,尚未形成良性长效机制,需从制度体系、环境经济手段、差别化补偿措施、农业补贴结构和宣传等5方面着手,推进农田保护经济补偿政策更好地服务生态环境。 相似文献

In this paper, we investigate the impact of oil prices on both aggregate and industry US real stock returns over the period 1973–2017. The empirical analysis contributes to the related literature introducing a state-dependent oil price (high and low) and the local projections approach. Our main finding is that, depending on the nature of the shock and industry, the negative effects of oil price shocks become exacerbated -and the positive effects get moderated- if oil prices are already high. 相似文献
