Medición,estructura y efectos de la informalidad en una microeconomía

En este artículo se mide el alcance del empleo informal y los ingresos no registrados que genera en una microeconomía caracterizada por una gobernanza deficiente. Se utilizan datos censales y de encuestas para estimar el número de trabajadores informales en Chipre Septentrional y analizar sus características durante el periodo 2004–2011. En su mayoría son nacionales no registrados en el régimen de seguridad social, inmigrantes ilegales o pluriempleados que no han declarado su segundo empleo. En términos de valor añadido, el tamaño estimado de la economía informal era del 9,1 y del 12,2 por ciento del PIB en 2006 y 2011, respectivamente.

The role of endowments,technology and size in international trade: new evidence from product-level data

Using product-level trade data, we empirically investigate the export patterns of more than 150 countries in their exports to the USA, Brazil, India, and Japan. We document strong evidence that exporters specialize according to their relative factor endowments, technology, and economic size. More developed, capital abundant countries are found to export products of higher unit values and a wider range of products to developed, emerging and developing markets. More developed, economically larger, and technologically advanced countries are also the major exporters of new products, spanning a wide range of product categories with high unit values. Our findings provide important insights into the macro phenomenon that a large proportion of the global trade takes place among developed economies, and that the latter are also major exporters to developing markets.     

资金来源、制度变革与国际经验借鉴:源自公共廉租房

2010年《政府工作报告》中指出,要争取用三年的时间,通过加强廉租住房等保障性住房建设,解决750万户城市低收入家庭和240万户林区、垦区、煤矿棚户区居民的住房困难问题。然而,在中国现行廉租房建设体制下,公共廉租房建设各利益方目标差异大,难以形成合力,从而造成建设资金难以得到满足。应借鉴西方发达国家公共住房建设的经验,通过改革政府财政制度、建立新的廉租房供给模式、创新公共廉租房融资模式等方式,逐步解决廉租房建设面临的资金困局。     

能源消费、二氧化碳排放与经济增长——基于二氧化碳减排成本视角的实证分析

本文基于VAR模型和脉冲响应函数分析方法,通过构建二氧化碳减排成本计算模型,定量分析了总能源消费和四种主要能源消费(煤炭、石油、电力、天然气)对宏观经济变量(产出、投资、就业)的影响.研究结论表明,基于各种主要能源消费的二氧化碳减排成本之间存在的差异性,施行燃料转换政策对于中国是一个很好的减排政策选择.     

Political patronage in Ukrainian banking1

This paper empirically investigates the link between political patronage and bank performance for Ukraine during 2003Q3–2005Q2. We find significant differences between politically affiliated and non‐affiliated banks. The data suggest that affiliated banks have significantly lower interest rate margins and increase their capitalization. Furthermore, we show that the level of activity of affiliated deputies in parliament has a positive (negative) impact on banks’ capitalization ratio (interest rate margin). Our findings imply, in line with the related literature, that political affiliation has important effects on banks’ behaviour.     

Persistence in International Inflation Rates

We test for fractional dynamics in inflation rates based on the consumer price index (CPI) for 27 countries and inflation rates based on the wholesale price index (WPI) for 22 countries. The fractional differencing parameter is estimated using semiparametric and approximate maximum likelihood methods. Significant evidence of fractional dynamics with long-memory features is found in both CPI- and WPI-based inflation rates for industrial as well as developing countries. Implications of the findings are considered, and sources of long memory are hypothesized.
