Business reform outcomes: Why so different?

Post-crisis policy making increasingly focuses on doing business reforms. We argue that the effects of those reforms will be different across countries. To understand the reasons for the reform outcome divergence, we advance a novel firm-size distribution (FSDs) argument. At the center of the argument is the fact that FSDs are different across countries and stable over time. Then, if a given doing business reform induces firms of different size to grow differently, this will produce a variety of reform outcomes across countries. To advance the argument, we set up a tractable general equilibrium (GE) model and study how firms of different size grow after a doing business reform. The model predicts that larger firms will grow faster than smaller firms after the reform. The model predictions are tested on the Enterprise Surveys (ES) data, merged with the Doing Business indicators. We confirm that firms of different size grow differently after a Doing Business reform. Thus, based on the notable differences of firm size distributions across countries, identical reforms to start, operate and close a business will produce a variety of reform outcomes across countries.     

What Survey Data Reveal about Price and Wage Rigidity in Portugal

This paper exploits the information collected from a survey conducted on a sample of Portuguese firms to study the patterns of firms’ price and wage adjustments and the extent of nominal price and wage rigidities. The evidence shows that the frequency of price changes varies substantially across sectors and depends on the intensity of competition, the share of labor costs and firms’ price reviewing behavior. The results also suggest that the constraint imposed by the presence of downward nominal wage rigidity is less important in firms where the fraction of permanent and high‐skilled workers is lower and the share of flexible pay components is higher.     

THE DEMAND FOR LIQUID ASSETS,CORPORATE SAVING,AND INTERNATIONAL CAPITAL FLOWS

The recent period of capital outflows from emerging economies has coincided with an increase in their corporate saving. In this paper, we model corporate saving as a demand for liquid assets by credit‐constrained firms in a dynamic open‐economy macroeconomic model. We find that the implications of this model are very different from standard models, because the demand for foreign bonds is a complement to domestic investment rather than a substitute. We show that this complementarity is at work when an emerging economy is on its convergence path or when it has a higher TFP growth rate. This framework is consistent with a number of stylized facts found in high‐growth, high‐investment emerging economies.     

Personal income taxation under mobility, exogenous and endogenous welfare weights, and asymmetric information

This paper analyses how governments should tax labour income accruing to a group of highly skilled and geographically mobile individuals who divide their time or career between several jurisdictions. The analysis differs from previous models on migration and taxation by addressing optimal regulation when agents work for several principals. Optimal taxation is developed for social welfare functions with exogenous and endogenous welfare weights. Marginal income taxes are applied for screening purposes, and the rates are lower with endogenous than with exogenous welfare weights. Received: 22 January 1998/Accepted: 3 July 1999)     

How much is too much: Does the size of income support transfers affect labor supply?

Cash transfer programs pursue mainly protective objectives, but can also impact rural livelihoods by inducing investments in productive activities and changing household labor allocation. We adopt a continuous treatment approach to quantify how households’ labor supply responds to transfer size. We find a shift from paid labor to own farm labor and find that the transfer size is well within a level that would have disincentive effects on time spent on own farm activities. The switch from paid to own farm labor occurs at lower levels of transfers for labor-constrained households, and at higher levels for non-labor constrained households.     

Global Climate Emergency: after COP24, climate science,urgency, and the threat to humanity

ABSTRACT

This Special Editorial on the Climate Emergency makes the case that although we are living in the time of Global Climate Emergency we are not yet acting as if we are in an imminent crisis. The authors review key aspects of the institutional response and climate science over the past several decades and the role of the economic system in perpetuating inertia on reduction of greenhouse gas emissions. Humanity is now the primary influence on the planet, and events in and around COP24 are the latest reminder that we live in a pathological system. A political economy has rendered the UNFCCC process as yet a successful failure. Fundamental change is urgently required. The conclusions contain recommendations and a call to action now.     

21世纪海上丝绸之路建设与我国沿海城市和港口的发展

"一带一路"计划集中体现了中国政府进一步扩大对外开放、提高对外开放水平的新理念。21世纪海上丝绸之路是"一带一路"的一个重要组成部分。21世纪海上丝绸之路建设将推动我国沿海城市和港口的发展,而沿海城市和港口的发展又将进一步为21世纪海上丝绸之路的延伸奠定坚实的基础。这一过程是双向的,不仅是一个向海外输出商品、资金、技术、服务标准、管理经验,甚至发展模式的过程,同时也是一个继续向海外学习、吸收、提升自我的过程,它体现的是一种海纳百川、对外开放、相互借鉴、互通有无、相互促进、共同发展的精神和文化。
