The role of innovation in venture capital: empirical evidence from European Union and EFTA countries

This article investigates the effects of innovation attempts on the venture capital and investment activity in the cases of the selected European Union plus European Free Trade Agreement countries using annual panel data and by controlling for real income growth and business sophistication. Our findings suggest that innovation has positively significant effects on venture capital in the cases without opt-out countries (United Kingdom and Denmark); however, these effects become negative in the cases with opt-out countries. Policy implications are provided in the conclusion section of this study.     

Regulating the banking industry in transition economies: Exploring interactions between capital and reserve requirements

This paper examines the ‘prudential' role of reserve requirements in transition economies using a general-equilibrium banking model. The analysis stresses the role that reserve requirements may play in enforcing an adequate level of bank capitalization in a context in which it is difficult to assess the true value of bank assets. The paper also explores the interactions that exist between capital and reserve requirements and the effect of these regulations on the financial structure of banks and on the level of credit and interest rates.     

城镇低保户医疗服务利用和医疗保障制度设计对就医行为的影响——基于兰州、西宁和白银城镇家庭调查数据的分析

解决低保户看病难问题事关社会底线公平。文章基于2005年三个西北城市的17 690个样本对低保户就医问题展开实证研究,分析结果表明,由于中国医疗机构扭曲的激励机制和偏重住院报销的给付结构,低保户和非低保户两个群体都倾向于自己购药处理日常病患,而减少了门诊利用,经常面临生存危机的低保户由此拖延病情直至病情严重;个人账户既不能横向分散不同人群的疾病风险,也不能纵向分散个人在生命周期不同阶段的疾病风险;职工基本医疗保险能够显著增加中青年低保户对住院服务的利用,但对老龄低保户没有效果。     

Law and social capital: Evidence from the Code Napoleon in Germany

I test whether legal institutions crowd-in social cooperation in the long-run, using the introduction of the Code Napoleon in parts of 19th century Germany as a historical experiment. I find that the application of the Code Napoleon is associated with higher levels of trust and cooperation today. This finding is robust to an identification strategy that uses only individuals located around a discontinuity in the number of years the Code Civil was used. Results from a falsification test that moves this discontinuity artificially, as well as the comparison of pre-treatment characteristics support the interpretation of a causal effect. In addition, regions around the discontinuity are similar in post-treatment economic development and inequality. On the contrary, the positive social consequences of the Code Civil manifest themselves in less political fraud in elections from 1871 to 1900, and in more “bridging” social capital in the 1920s.     

Income inequality and financial reform in Asia: the role of human capital

We investigate whether financial reform can reduce income inequality in Asia, with particular emphasis on the role of human capital. Extending Galor and Zeira (1993), we demonstrate that financial reform is effective in reducing income inequality, and the effect is more profound in a country with higher human capital. Using the data for 18 countries in Asia, the region with the most promising financial reform, we confirm our theoretical finding. In addition, among disaggregated financial reforms, lift of credit control, better banking supervision and security market development seem to be significantly associated with reduction of income inequality.     

Regional productivity variation and the impact of public capital stock: an analysis with spatial interaction,with reference to Spain

In this article, we examine whether variations in the level of public capital across Spain's Provinces affected productivity levels over the period 1996 to 2005. The analysis is motivated by contemporary urban economics theory, involving a production function for the competitive sector of the economy (‘industry’) which includes the level of composite services derived from ‘service’ firms under monopolistic competition. The outcome is potentially increasing returns to scale resulting from pecuniary externalities deriving from internal increasing returns in the monopolistic competition sector. We extend the production function by also making (log) labour efficiency a function of (log) total public capital stock and (log) human capital stock, leading to a simple and empirically tractable reduced form linking productivity level to density of employment, human capital and public capital stock. The model is further extended to include technological externalities or spillovers across provinces. Using panel data methodology, we find significant elasticities for total capital stock and for human capital stock, and a significant impact for employment density. The finding that the effect of public capital is significantly different from zero, indicating that it has a direct effect even after controlling for employment density, is contrary to some of the earlier research findings which leave the question of the impact of public capital unresolved.     

Financial development and the share of imported capital goods in developing countries: firm-level evidence

Firm-level estimations across a sample of seven developing countries suggest that a higher firm’s leverage – a proxy for credit constraints – reduces the share of imported capital goods in total capital expenditures. This result holds across different models such as a two-limit tobit and a fractional logit model. It is also confirmed after controlling for unobserved firm heterogeneity, state dependence or when using the share of property in total assets as an alternative credit constraint indicator. The results also indicate that the importance of credit constraints is significantly reduced in financially more developed countries.     

Systems valuing of natural capital and investment in extensive pastoral systems: Lessons from the Patagonian case

In Patagonian (Argentina) wool production systems, historical performance records, observed landscape changes, and long-term demographic modeling of sheep flocks, indicate that non-sustainable ecological and economic dynamics have developed during recent decades. In order to elucidate possible causes of these trends, a dynamic model of the wool production system including basic ecological and economic feedback mechanisms was applied to the analysis of alternative investment policies. The values of the various components (ewes, forage, soil) of natural capital (NC) involved in the production systems were estimated in this study through a systemic approach and their losses during wool production cycles were incorporated in their financial analysis. Our results indicate that external investment in increasing the ewe stocks (a common practice in these systems) is not sustainable in time unless a simultaneous external investment in forage NC is performed. More specifically, external investment to increase in 20% the ewe stocks would be expected to generate positive net cash flows during 6-8 years, if due account is taken from the losses of NC produced. Successive investments of the same sort would generate increasingly shorter periods of positive cash flows or even negative results after 15-25 years. Re-investment of a fraction of the net revenues obtained through wool sales in the reposition of forage resources also proves to be a non-sustainable policy. External investment on forage resources at about a 10:1 ratio with respect to investments in the ewe stock would produce positive net cash flows sustainable in time. It is concluded that sustainable investment policies in extensive range systems of Patagonia should consider the ecological-economic relations and feedbacks existing between forage consumption by ewes and ewe natality/soil erosion controls exerted by forage and market behavior. The structure of analysis of investment policies on extensive pastoral systems of the Patagonian Monte here proposed seems valuable to be extended to other regions with similar ecological-economic characteristics.     

Dynamics of social trust and human capital in the learning process: The case of the Japan garment cluster in the period 1968–2005

This paper examined the ways and the extent to which human capital and social trust are associated with the learning process of a manager in making operations decisions through experience. To this end, using a data set originally and purposively constructed by the author, I investigated the development and transformation of the garment industry cluster region of Kojima, Japan. The major findings through statistical estimations are as follows. (1) In the cluster development stage, the social trust of an enterprise and its manager's experiences in firm operations could be regarded as forming a complementary association. (2) In the stage following cluster development, however, a manager's human capital as accumulated through schooling and personal experience, instead of social trust, become complementary.     

Spillovers and absorptive capacity in the decision to innovate of Spanish firms: the role of human capital

This paper investigates whether the existence of knowledge spillovers and the capacity of firms to assimilate them, which we relate with R&D intensity and some human resource management practices, are associated with the decision to innovate of Spanish firms. In order to do this, we employ data from the ‘Central de Balances’ database, which covers both manufacturing and services firms during the period 2003–2007, and use an estimator proposed by Wooldridge [2005. Simple solutions to the initial conditions problem in dynamic nonlinear panel data models with unobserved heterogeneity. Journal of Applied Econometrics 20, no. 1: 39–54] for dynamic random effects discrete choice models. The empirical exercise provides evidence on the positive link between spillovers and the innovative behaviour of companies, not just for the knowledge generated in the same industry, but also for that generated in the same region or by the public sector. Moreover, this link is stronger for those firms with a higher capacity to absorb those spillovers. This ability not only works through firms’ R&D capabilities, but also through factors such as the quality of the labour force, the share of temporary employment and the amount of resources spent in training. In addition to these factors, we find that innovation performance exhibits a high degree of inertia. Further, some other observed firm characteristics, such as size, sales growth, export behaviour, sector capital intensity or financial structure variables, are also found to be relevant determinants of the likelihood of innovation.     

Productivity growth of newly industrializing economies in heterogeneous capital goods markets: the case of the Korean machinery and equipment industry

Although many previous studies have investigated the economic growth of East Asian countries from the perspective of productivity growth, they have adopted a limited focus only on the national level or on the aggregated level and have overlooked the heterogeneity at the disaggregated level. Furthermore, only a few studies have examined the sources of the remarkable growth and trade performance of the Korean machinery and equipment industry, despite its importance for sustainable growth of national economy. Therefore, we investigated the Total Factor Productivity Growth (TFPG) of the Korean machinery and equipment industry and its 12 sub-sectors from 1970 to 2012 using the stochastic frontier production approach. As a result, we found that the industry has achieved labour input-driven TFPG largely due to technical progress. This is contrary to the previous result that East Asia has expanded the production frontier by capital accumulation. In contrast, in some sub-sectors, scale effect and allocation efficiency have driven TFPG. We also found distinctive patterns of TFPG across different sub-sectors from the perspectives of the effect of input factors and the pattern of technical progress. These results imply that policy makers should consider industry-specific policy designs that incorporate the specific characteristics of individual sub-sectors.

Coping with deflation and the liquidity trap in the eurozone: A post Keynesian approach

The ghost of deflation is once again one of the main worries of policymakers. Recently deflation is indeed characterizing the eurozone. The renewed concern about deflation is due in part to the historical association of deflationary episodes with financial crises, recession, stagnation, and even depression. In deflationary conditions, nominal interest rates are more volatile because uncertainty increases and they may come close to their lower limit of zero: If a “liquidity trap” is at work, monetary policy is incapable of stimulating aggregate demand. This article seeks to show that to avoid a “Japanization” of the eurozone it is urgent to implement adequate economic policies in accordance with the post Keynesian approach. The European Central Bank in recent times has tried to do its best to save the situation through espansive monetary policies adopting both quantitative and qualitative easing. Unfortunately, these kinds of policies have tended more to prevent the recession from becoming far worse than enabling a significant fight against deflation and promoting economic recovery. Conventional and unconventional approaches in economic policy are investigated with a critical eye and contrasted with the theoretical insights suggested by post Keynesians.

Estimates of the direct and indirect cost savings associated with heart disease that could be avoided through dietary change in the United States

Aims: Diets high in saturated fat are associated with elevated risk of heart disease. This study estimates the savings in direct (medical care) costs and indirect (job absenteeism) costs in the US from reductions in heart disease associated with substituting monounsaturated fats (MUFA) for saturated fats.

Materials and methods: A four-part model of the medical care cost savings from avoided heart disease was estimated using data on 247,700 adults from the 2000–2010 Medical Expenditure Panel Survey (MEPS). The savings from reduced job absenteeism due to avoided heart disease was estimated using a zero-inflated negative binomial model of the number of annual work loss days applied to data on 164,577 adults from the MEPS.

Results: Estimated annual savings in medical care expenditures resulting from a switch from a diet high in saturated fat to a high-MUFA diet totaled ～ $25.7 billion (95% CI = $6.0–$45.4 billion) in 2010, with private insurance plans saving $7.9 billion (95% CI?=?$1.8–$14.0 billion), Medicare saving $9.4 billion (95% CI?=?$2.1–$16.7 billion), Medicaid saving $1.4 billion (95% CI?=?Aims: Diets high in saturated fat are associated with elevated risk of heart disease.

The annual savings in terms of reduced job absenteeism ranges from a lower bound of $600 million (95% CI?=?$100 million to $1.0 billion) to an upper bound of $1.2 billion (95% CI?=?$0.2–$2.1 billion) for 2010.

Limitations: The data cover only the non-institutionalized population. Decreased costs due to any decreases in the severity of heart disease are not included. Cost savings do not include any reduction in informal care at home.

Conclusions: Diets high in saturated fat impose substantial medical care costs and job absenteeism costs, and substantial savings could be achieved by substituting MUFA for saturated fat.

医疗服务递送机制中主体利益关系及扭曲矫正——基于政府职能的视角

医疗服务递送机制中涉及到医疗服务机构、医生、药企和患者四方利益主体。当前我国这些利益主体之间种种不合理的利益"合作"与"冲突",均与医疗服务递送机制中政府职能的缺位和错位存在着直接关系。在进一步深化医改的过程中,我国政府应当正确地履行好理应承担的公共职能,即加强对卫生资源的合理规划与配置;加大对公立医院的财政投入并优化对其补偿机制;加强对医疗服务机构与药品行业的监管;加强医药信息披露机制建设;鼓励医药卫生服务市场公平竞争,并放弃不适当的医药价格管制。     

上海近代崛起的人力资本因素分析——1933年上海人力资本的估算及与全国的比较

居于中国近代化中心地位的上海,当时的人力资本状况与近代化进程之间有何联系?文章运用现代人力资本估算中的LIHK方法对1933年上海和中国的人力资本进行了估算和比较。结果表明:上海在平均人力资本上具有极其显著的优势。1933年,上海人力资本总存量占当年全国人力资本总存量的26%以上,其平均人力资本约为全国平均人力资本的33倍。与物质资本相比,上海1933年平均人力资本仅及平均物质资本的27.7%,但这一比例仍大大高于全国的水平。     

Clinical and economic benefits of professional CGM among people with type 2 diabetes in the United States: analysis of claims and lab data

Background: It is estimated that one in 10 people in the US have a diagnosis of diabetes. Type 2 diabetes accounts for 95% of all cases in the US, with annual costs estimated to be $246 billion per year. This study investigated the impact of a glucose-measuring intervention to the burden of type 2 diabetes.

Objective: This analysis seeks to understand how professional continuous glucose monitoring (professional CGM) impacts clinical and economic outcomes when compared to patients who are not prescribed professional CGM.

Methods: This study utilized a large healthcare claims and lab dataset from the US, and identified a cohort of patients who were prescribed professional CGM as identified by CPT codes 95250 and 95251. It calculated economic and clinical outcomes 1 year before and 1 year after the use of professional CGM, using a generalized linear model.

Results: Patients who utilized professional CGM saw an improvement in hemoglobin A1C. The “difference-in-difference” calculation for A1C was shown to be –0.44%. There was no statistically significant difference in growth of total annual costs for people who used professional CGM compared to those who did not ($1,270, p?=?.08). Patients using professional CGM more than once per year had a –$3,376 difference in the growth of total costs (p?=?.05). Patients who used professional CGM while changing their diabetes treatment regimen also had a difference of –$3,327 in growth of total costs (p?=?.0023).

Conclusion: Significant clinical benefits were observed for patients who used professional CGM. Economic benefits were observed for patients who utilized professional CGM more than once within a 1-year period or who used it during a change of diabetes therapy. This suggests that professional CGM may help decrease rising trends in healthcare costs for people with type 2 diabetes, while also improving clinical outcomes.     

Public provision of health insurance and aggregate saving in an overlapping generations model with endogenous health risk: The South Korean case

This paper examines the effect of expanding public health insurance in South Korea on medical expenditures and aggregate saving using an overlapping generations model with endogenous health risk. South Korea had a substantial underinsured population, which is aging rapidly. Higher public health insurance benefits reduce individual medical expenditure and health risks but lead to a modest decline in individual and aggregate saving. Even after the expansion, the medical care coverage remains incomplete, and the elderly face a substantial risk of out-of-pocket medical expenditures.
