State‐Dependent Forward Guidance and the Problem of Inconsistent Announcements

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.

Public finance and the optimal speed of transition*

We develop a general equilibrium model that jointly considers the influence of capital accumulation constraints and of labour market frictions on the process of transition. We endogenize the economic and budgetary costs of different government policies and show that, early in transition, governments ought to subsidize state firms. Provided that intertemporal commitment is feasible, this policy limits the initial output fall, which relaxes capital accumulation constraints, accelerates transition, and increases welfare. Moreover, by resorting to indirect – instead of direct – taxes, governments can bring the path of transition closer to the first best. Yet, political pressures may induce a policy of suboptimal subsidization.

Do small businesses adjust their capital structure? Evidence from the global financial crisis in Japan

We investigate the extent to which small businesses adjust their capital structures to target levels when their leverage increases substantially during a financial crisis. We examine Japan's Emergency Credit Guarantee (ECG) program during the 2008 global financial crisis. The increased leverage from the use of the ECG program during the crisis increased the probability of default. Additionally, small businesses adjusted their leverage ratios to the target range before the crisis. However, such adjustments were weak during and after the crisis, particularly for target firms in the ECG program.     

论我国行政指导的运行及制度构想

行政指导已成为现代市场经济国家行政发展的新趋势,在我国也有了社会经济背景、政府行政背景、民众意识背景和法学理论背景等方面的运行基础。行政指导在我国行政实务中开始得到广泛运用,其独特作用已经显露,但实践和制度上仍有很多不可回避的问题,需要对行政指导在实体规范、程序规范、监督救济机制以及配套规范方面进行制度设计。     

高铁开通、要素禀赋与区域经济增长——以贵州省为例

基于2008-2018年贵州省9个地级市和自治州的面板数据,实证检验高铁开通对区域要素禀赋与经济增长的影响。结果表明:高铁开通在总体上促进了贵州省区域经济增长,提高了劳动力要素的相对丰裕程度。然而,高铁开通并未表现出技术溢出作用,反而降低了劳动力和资本要素的边际生产率,对要素禀赋结构优化和区域经济长期发展产生不利影响。基于此提出,应因地制宜科学规划高铁建设,推进科学技术创新,加强高素质人才培养与引进,优化营商环境,提升社会保障水平,以发挥高铁的扩散效应,降低聚集效应,进而改善要素禀赋结构,促进区域经济协调发展。
