We focus on the role of the government in the provision of investment in China, through the medium of a Dynamic Stochastic General Equilibrium model of the economy in which the form of the production function reflects this governmental role. Using indirect inference, we estimate and test for the elasticity of substitution between government and nongovernment capital in both Constant Elasticity of Substitution (CES) and Cobb–Douglas technologies. The results underscore the strong substitution relationship between government and nongovernment capital from 1949, supporting CES rather than the Cobb–Douglas technology. They also show that the orientation of public investment changed after the start of the ‘Socialist Market Economy’ in 1992: government capital became more complementary to nongovernment capital as it focused more on infrastructure and withdrew from industrial production, intervening only in times of crisis, for stabilization purposes, indirectly via the state banks.  相似文献

The role of European businesses in addressing environmental issues and climate change has taken center stage with the European Green Deal. With increasing attention to the effect of board gender diversity (BGD) on firms' environmental performance, the question arises whether BGD has any influence on carbon emissions. Based on legitimacy and critical mass theory, this study empirically investigates the impact of BGD on firms' carbon performance (CP), based on total carbon emissions intensity. The paper relies on two-stage least squares (2SLS) regressions with instrumental variable (IV) and a two-step generalized method of moments (GMM) system approach to analyze a cross-country sample of 3123 observations from non-financial firms in the European STOXX600 index over the 2009–2018 period. Our findings add to the growing empirical evidence twofold: (1) there is a robust linear and positive relationship between BGD and CP, whereas some indication of a U-shaped relationship is found; and (2) we find that a critical mass of at least two women directors needs to be reached to increase CP. Our research results contribute to the current discussion on sustainable corporate governance, especially in the European capital market, and have implications for researchers, business practice, and regulatory issues alike.  相似文献

This paper further enhances the analytical power of Delphi methodology by identifying the advantages, disadvantages and challenges presented by increasing diversity among panel groups. Using Delphi survey data on the future of nuclear energy in France, we analyze the origins of the variety of judgments within and between two panels: one of experts and one of laypeople. We investigate the determinants of the stability of those opinions both in one given round and over several rounds of opinion-formation. We reach an apparently paradoxical conclusion: that non-expert judgment is less stable, but not necessarily less accurate, than that of experts, judgments on the part of experts sometimes being clouded by self-interest. Apart from highlighting some factors underlying the controversy over nuclear power, our paper calls for greater participatory democracy in Delphi panels, but also demonstrates the limits of such an extension.  相似文献

In any nonlinear “difference-in-differences” model with strictly monotonic transformation function, the treatment effect is the cross difference of the observed outcome minus the cross difference of the potential non-treatment outcome, which equals the incremental effect of the interaction term coefficient.  相似文献

Previous studies have suggested that more liberal abortion laws should lead to a decrease in marriage rates among young women as ‘shotgun weddings’ are no longer necessary. Empirical evidence from the United States lends support to that hypothesis. This article presents an alternative theory of abortion access and marriage based on the cost of search which suggests that more liberal abortion laws may actually promote young marriage. An empirical examination of marriage data from Eastern Europe shows that countries that liberalized their abortion laws saw an increase in marriage rates among nonteenage women.  相似文献

Professor Bruce Kaufman's look back at two seminal books published at the beginning of the strategic HRM field and examination of two recent books to trace the evolution of the field identifies some issues, but ones with which the field has dealt for a number of years. His choice of our book HRM and Performance provided the wrong target, and consequently his analysis seemed to miss the mark. © 2015 Wiley Periodicals, Inc.  相似文献

Global bond markets, along with banks and governments, are the main source of funding for investment in environmentally friendly infrastructure and the transition to clean energy. Although such bonds are a relatively recent innovation, the green bond market has grown rapidly from its start in 2008 to around $800 billion in outstanding issues. The problem, however, is that green bonds, which represent less than 1% of global bond markets, have been issued disproportionately by government‐sponsored entities, corporations, and municipalities in developed markets. In the emerging market countries where the infrastructure investments are most needed, they barely exist. The authors describe a new investment vehicle, called the AP EGO fund, whose mission and MO are to channel the vast global pools of institutional savings that are now invested in low or (even negative) yield fixed‐income assets—as much as $17 trillion in 2019—to higher‐return emerging markets green investments, in particular sustainable infrastructure, by creating a new asset class: emerging‐market green bonds issued by banks. The AP EGO fund is premised on and involves a reworking of the public‐private partnership (PPP) into a form they call the global public‐private investment partnership (or GPPIP). Unlike the PPP, which combines a public agency with a private operator, the GPPIP has four instead of just two partners. In addition to the standard public agency and the private concession operator, there is a development bank—in this case the International Finance Corporation (IFC), which is the financial markets affiliate of the World Bank—and private investors that include emerging‐market banks as well as global institutional investors. Along with the mediating role played by a public agency like the IFC, the AP EGO Fund is fundamentally different from other PPPs in that it takes the form of a special purpose securitization vehicle whose shares are backed by a pool of green bonds issued by emerging market banks in multiple emerging market countries. And besides its application to a new asset class, the fund also breaks new ground by applying a securitization technique with a fund structure designed with an embedded “first‐loss” protection to a global pool of green bonds originated in emerging market economies. By means of this structuring, the green‐bond‐backed fund shares issued by the AP EGO are now providing developed market institutional investors with somewhat higher‐yielding fixed income securities that nevertheless carry an investment‐grade rating.  相似文献

Our analysis of US state-level data on an annual frequency, from 1976 to 2008, sheds new light on a plausible causal link between infrastructure investments, namely public spending on highways, and income inequality. This causal relationship is drawn out using the number of seats in the US House of Representatives Committee on Appropriations (HRCA) as an instrument to identify quasi-random variations in state-level spending on highways. An exogenous pattern which emerges when a state gains an additional member to the HRCA is that it is allocated with new federal grants. This increase in federal transfers for infrastructure financing results in slashing of expenditures on highways and a crowding-out effect of federal funding for state investments on highways. Spending cuts on highways produced by a new HRCA member being attained by a state can unwittingly cause income inequality to rise over a short 2-year time horizon. Similar challenges with decentralized development to finance infrastructure via federal transfers to state and sub-national governments may be encountered by other industrially advanced, emerging and low-income developing economies. US data over the mentioned period reveal a strong positive correlation with state spending on highways and wages paid for construction jobs. Suggestive evidence indicates that the construction sector also plays an important role in the transmission channel from a rise in state spending on highways to lowering income inequality, albeit during specific intervals, as opposed to on a long-term basis.  相似文献

Abstract. Rising wage inequality in the United States and Britain and rising continental European unemployment have led to a popular view in the economics profession that these two phenomena are related to negative relative demand shocks against the unskilled, combined with flexible wages in the Anglo-Saxon countries, but wage rigidities in continental Europe ('Krugman hypothesis'). This paper tests this hypothesis based on seven large person-level data sets for the 1980s and the 1990s. I use a more sophisticated categorization of low-skilled workers than previous studies, which exhibits differences between German workers with and without apprenticeship training, particularly in the 1980s. I find evidence for the Krugman hypothesis when Germany is compared with the United States. However, supply changes differ considerably between countries, with Britain experiencing enormous increases in skill supply explaining the relatively constant British skill premium in the 1990s.  相似文献
