Mean reverting financial leverage: theory and evidence from Pakistan

Grounding concepts of the two competing theories of capital structure (trade-off theory, pecking order theory) are quite opposite to each other. Trade-off theory claims that there is an optimal (target) capital structure and firms try to achieve that optimal (target) point. Whereas pecking order theory argues that there is no optimal (target) capital structure but the firms follow a specific pattern of financing. Using the two competing theoretic frameworks, this study applies Fisher-type panel unit root test to an unbalanced panel data of 13 115 firm-year observations of nonfinancial firms listed on Karachi Stock Exchange Pakistan spread over 38 years (1973–2010). Overall panel test results, for short-term, long-term, as well as total leverage support trade-off financing behaviour while individual firm results do not. Individual firm results show that only 16% of the firms have short-term target, 25% of the firms have long-term target and 12% of the firms have total target leverage ratio. Further, industry results explain that most of the industries do have target leverage ratios and classification of data into profitable and lossmaking firm-year observations explains that profitable firms clearly follow trade-off financing behaviour while the results for lossmaking firms do not support trade-off financing behaviour. Our study indicates that it is important for the government to ensure policies to develop well-balanced financial markets and to improve accountability systems.     

产业结构调整的资本市场约束

近年来,资本市场繁荣,资本市场收益率激增,产业中的微观企业成为了资本市场的主体,希望在资本市场中迅速实现资本增值,为企业自身的产业结构合理发展、优化升级创造资本条件。然而,这种行为致使产业结构调整产生波动,产业内部的合理化受到阻碍,产业之间的优化升级遇到鸿沟。甚至出现了产业结构不合理,产业发展倒退现象。资本市场的快速发展最终对产业结构调整产生了投资约束。     

On the heterogeneous impact of public capital and current spending on growth across nations

This paper captures the heterogeneous impact on growth, of public capital and current spending, for 15 developing countries. Using the GMM system panel estimator, we show that countries with substantial public capital (current) spending have strong negative (positive) growth effects.     

The dynamic impact of intellectual capital on firm value: evidence from China

We examine the dynamic relationship between intellectual capital (measured by human capital and organizational capital) and firm value of Chinese listed firms. We do causality identification using system GMM and IV estimation, and find no significant relation between human capital and firm value, but organizational capital positively affects firm value with a lag. Our findings are robust to firms with different property rights, of different sizes, or in different industries, with the only exception of capital-intensive firms, in which human capital has a significant influence on firm value. The results imply that the improvement of organizational system plays a more important role in raising the value of a firm in a typical developing country, like China.     

Areal differentiation of virtual water for agricultural products and its effect on regional agricultural structure adjustment in China： 1995-2007

With a vast territory, the space-time distribution of water resources is uneven in China. There is a great dif ference in natural conditions and farmland management of agricuttural production in different regions. The areal differentiation of agricultural products virtual water is obvious. Comparison with the agricultural products virtual water from 1995 to 2007 in China shows an increase in the first ten vears and a little decrease in recent years. There has been a tendency of increase all the time in Northeast and Northwest. but a decrease after an increase firstly in other regions. The virtual water offood crops is the maximum which accounts for more than 70% in China. and that of vegetables is in a fast growth. The proportion of agricultural products virtual water to the total water resources in each region has a large difference, showing the imbalance of agricultural water in different regions, which accounts for 50%-90% in Northeast, and 125%-185% in North China. Under the guidance of virtual water strategy, based on the differences of resource endowment, each region should adjust agricultural structure, decide production by water, and select water suitable crops. In water-rich region, agricultural produets of high water consumption should be planted appropriately, which will make full use of the abundant local water resources. In water-shortage region the crop production of high water consumption and low efficiency should be depressed, and that of low water consumption and high efficiency should be supported and increased. It will achieve reasonable disposition of water resources, promote ecological restoration and environmental protection, as welt as ensure food security.     

资本结构动态调整研究综述

目前,很多学者纷纷采用动态资本结构模型,来证实资本结构具有动态调整的特性.资本结构动态调整理论认为公司并不是在任何时候都处于最优资本结构状态,随机事件的发生和调整成本的存在使得企业的实际资本结构偏离了其目标资本结构.企业在不断地向目标资本结构进行部分调整,且调整速度与企业规模、盈利能力等企业特征变量,与资本市场类型等宏观经济变量和企业偏离目标资本结构的程度等有关.     

A weighty issue revisited: the dynamic effect of body weight on earnings and satisfaction in Germany

We estimate the relationship between changes in the body mass index (bmi) and wages or satisfaction, respectively, in a panel of German employees. In contrast to previous findings, our dynamic models indicate an inverse u-shaped association between bmi and wages. As the implied maximum occurs in the ‘overweight’ category, the positive trend in weight may not yet constitute a major limitation to productivity. Further investigation points out a stronger association among young workers and workers with jobs that are less protected. Work satisfaction of young workers is associated with bmi beyond the effect of earnings.     

The short- and long-run impacts of financial crises on youth unemployment in OECD countries

The impact of financial crises on the youth unemployment rate (YUR), compared to the total unemployment rate (UR), is estimated for a panel of OECD countries over the period 1981–2009, using bias-corrected dynamic panel data estimators of short- and long-run coefficients. Both YUR and UR are found highly persistent. Also, short- and long-run effects of financial crises on YUR are significantly large, respectively, some 1.9 and 1.5–1.7 times higher than the short- and long-run effects on UR. Similar results are found for the unemployment impacts of GDP growth lagged 1 year and institutional variables. These results are robust to various dynamic specifications.     

中国工业化、城镇化对能源强度的影响——基于动态面板数据模型的研究

以中国30个省市自治区作为横截面单元,将全国分为三个部分,利用各横截面单元2000~2011年组成的面板数据,建立动态面板数据模型分析工业化、城镇化对能源强度的影响。结果表明:城镇化水平对我国不同地区的影响有显著差异,在东部地区,提高城镇化水平能有效降低能源强度,而就全国范围和中西部地区而言,城镇化水平的提高阻碍了能源强度的降低;工业化水平的提高推动了能源强度的上升。根据得出的结论,文章还对降低能源强度提出了相应的建议。     

The impact of housing market disturbances on the US financial system: a pre-crisis analysis

A common critique of the Federal Reserve over the past crisis is that it should have better anticipated the impact of the run-up in home mortgage debt and the subsequent housing market crash on the financial system. As a result, the Federal Reserve should have moved much more quickly to shore up financial markets. Our article tests the hypothesis that the impact of the housing market crash on the financial system could have been anticipated. Using a VAR model along with impulse response functions and variance decompositions, we examine the link between housing market mortgage debt shocks and the financial intermediaries’ credit market behaviour. We find important connections between key macroeconomic variables and the credit behaviour of these financial institutions. However, using the pre-crisis data, we find that housing market debt shocks fail to have an impact on the credit markets accessed by these firms. These results support the notion that the impact of this crisis on the financial system could not have been anticipated given the information available at the time.     

国际资本流动对房地产价格的影响——基于中国的实证检验:1998-2006

Taking the inflation into consideration and making use of the quarter data of the actual foreign investment, housing and land prices in China from 1998 to 2006, this paper examines the relationship between housing prices and international capital flows using Error Correction Model (ECM) and Granger causality test. Results show that in the short run, the increase of housing prices attracts the inflow of foreign capitals; in the long run, foreign capitals help to boost the rise of housing prices. Therefore, at present, Chinese government must impose effective restrictions on the flow of foreign capital into the real estate market. __________ Translated from Caijing Wenti Yanjiu 财经问题研究 (Research on Financial and Economic Issues), 2007, (3): 55–61     

The sustainability and transition of economic growth in China：from a perspective of factor structure

After more than 20 years＇ high speed growth, the sustainable growth of Chinese economy faces serious limitation of resources and factors now and in the future. In order to maintain the economic growth. China has to trans-form the way of economic growth, Based on the analysis on the related theories of economic growth and the structural transformation in factors of production, this paper proposes that the transformation of the economic growth way has to impel the optimization and the promotion of the utilization structure of factors of production. Finall.v, based on the analysis of the necessity to change the pattern of economic growth, this paper proposes＇ the strategic measures to promote the continuous economic growth and the transformation of patterns of economic growth.     

Study on agricultural structure and non-point source pollution： a case in Dapu Town of Yixing City

The water body of Taihu Lake has been eutrophicated because of area-source pollution. 83% of the total nitrogen and 84% of the total phosphorus of the pollutant that have washed into Taihu Lake originated from the fertilizer of crop land, rural animal husbandry and living sewage and rubbish in rural area. The goal of adjusting agricultural structure is to improve agricultural development, and to increase the peasants＇ income by planting non-grain crop, centralizing animal husbandry, and intensifying aquaculture, etc. It is necessary to research on the influences of agriculture industrial structure on area-source pollution. This paper studies a case of Dapu Town in Yixing City, which is a typical drainage place beside Taihu Lake. On the basis of the analysis on the status quo of area-source pollution and agriculture industrial structure in Dapu Town, the conflicts between them are discussed. Non-grain crop production with a great deal of fertilizer and developing aquaculture with a great deal of organic pollutant, which are directly discharged, make area-source pollution more serious and accelerate the eutrophication in Taihu Lake. This paper suggests taking corresponding technological measures and policies, which have been tested in Dapu Town and demonstrated in Taih, Lake area.     

The effect of marginal tax rates on taxable income: a panel study of the 1988 tax flattening in Canada

Federal tax reform in 1988 flattened the Canadian personal income tax schedule, changing the marginal tax rates for many individuals. Using methods similar to those applied by Auten and Carroll [Rev. Econ. 81(4) (1999) 681] in the study of the effects of the 1986 U.S. Tax Reform Act, we estimate the responsiveness of income to changes in taxes to be substantially smaller in Canada. However we find evidence of a much higher response in self-employment income, in the labor income of seniors and from those with high incomes.     

The economic impact of galantamine vs placebo: An analysis based on functional capacity in a Swedish cohort study

Abstract

Objective:

To analyse the economic impact of galantamine, based on basic activities of daily living (ADL).

Methods:

Data were derived from Swedish patients enrolled in a 6-month placebo-controlled trial of galantamine (GAL-INT-1; n?=?80), and from the Kungsholmen–Nordanstig Project, a longitudinal study of 919 elderly persons in Sweden. Basic ADL were assessed using the Katz’ Index of Independence in Activities of Daily Living (ADL) (number of ADL lost [dependency in 0, 1–2, 3–4, or 5–6 ADL]). Costs were appraised based on regression analysis and on costs directly linked to ADL. Six-month costs for galantamine and placebo were calculated.

Results:

In the regression analyses, each increase in a Katz stage was associated with an annual cost increase of SEK 81,415–83,683 (～€8000). Results were similar using stage-specific costs. Overall, there was a small, non-significant numerical cost benefit for galantamine indicating cost neutrality.

Limitations:

The small number of Swedish patients in the GAL-INT-1 study, which was not powered for economic outcomes, limits the statistical power of the analysis. In addition, long-term outcomes are difficult to assess in persons with dementia because of practical and logistical problems.

Conclusions:

The benefits of galantamine in patients with AD can be achieved with no increase in cost. Combined with positive effects in terms of outcome, treatment with galantamine can be regarded as cost-effective using a cost–consequence approach.
