Rising income inequality has recently come centre‐stage as a core societal concern for rich countries. The diagnosis of the forces driving inequality upwards and their relative importance remain hotly contested, notably with respect to the roles of globalization versus technology and of market forces versus institutions and policy choices. This survey provides a critical review and synthesis of recent research. The focus is on income inequality across the entire distribution, rather than only on what has been happening at the very top. We pay particular attention to include what has been learned from the analysis of micro‐data, to ensure that the coverage is not unduly US‐centric and to analyses of the interrelations between the different drivers of inequality. The marked differences in inequality trends across countries and time periods reflect how global economic forces such as globalization and technological change have interacted with differing national contexts and institutions. Major analytical challenges stand in the way of a consensus emerging on the relative importance of different drivers in how income inequality has evolved in recent decades. 相似文献

We employ a recent time‐varying cointegration test to revisit the usefulness of long‐run money demand equations for the ECB, addressing the issue of their instability by means of a model evaluation exercise. Building on the results, we make a twofold contribution. First, we propose a novel stable money demand equation relying on two crucial factors: a speculative motive, represented by domestic and foreign price‐earnings ratios, and a precautionary motive, measured by changes in unemployment. Second, we use the model to derive relevant policy implications for the ECB, since excess liquidity looks more useful for forecasting stock market busts than future inflation. Overall, this evidence points to (i) a possible evolution of the monetary pillar in the direction of pursuing financial stability and (ii) the exclusion of a sudden liquidity–driven inflationary burst after the exit from the prolonged period of unconventional monetary measures. 相似文献

This paper presents the first comparison of the accuracy of density forecasts for stock prices. Six sets of forecasts are evaluated for DJIA stocks, across four forecast horizons. Two forecasts are risk‐neutral densities implied by the Black–Scholes and Heston models. The third set are historical lognormal densities with dispersion determined by forecasts of realized variances obtained from 5‐min returns. Three further sets are defined by transforming risk‐neutral and historical densities into real‐world densities. The most accurate method applies the risk transformation to the Black–Scholes densities. This method outperforms all others for 87% of the comparisons made using the likelihood criterion. 相似文献

This article analyzes in detail the virtue of practical wisdom as described by Thomas Aquinas, and on this basis it develops a comprehensive framework to enrich Authentic Leadership theory, establishing the virtue of practical wisdom as foundational for the authentic leader’s behavior and character development, and highlighting shortfalls that may stem from vices opposed to it. The goal of the article is two-fold: First, it seeks to fill a void on the role of virtues–and in particular practical wisdom–in leadership studies; second, it aims to show how cultivating the virtue of practical wisdom as described by Aquinas promotes the development of exactly those traits that are characteristic of an authentic leader, offering a set of propositions delineating these correlations. 相似文献

The aim of this paper is to assess—on both theoretical and empirical grounds—the two main views regarding the money creation process, namely the endogenous and exogenous money approaches. After analysing the main issues and the related empirical literature, we will apply a vector autoregression model and a vector error‐correction model methodology to the United States for the period 1959–2017 to assess the causal relationship between a number of critical variables that are supposed to determine the money supply, that is, the monetary base, bank deposits, bank loans and the nominal level of economic activity. The empirical analysis supports several propositions related to the endogenous money approach. In particular, it shows that for the United States in the years 1959–2017 (a) bank loans determine bank deposits and (b) bank deposits in turn determine the monetary base. Our conclusion is that money supply is mainly determined endogenously by the lending activity of commercial banks and the nominal level of economic activity. 相似文献

Following León‐Ledesma and Thirlwall (2002a), this paper examines the hypothesis that the natural rate of growth of the Italian regions is endogenous to and positively affected by the actual growth rate. Relying on fixed‐effects and SUR estimation techniques and using annual data for the 20 Italian regions over the period 1977–2003, we find strong support for the endogeneity hypothesis suggesting that faster actual growth raises the natural rate of growth of the average Italian region by about 3–3.7 percentage points. Furthermore, in line with recent findings in the literature, our analysis provides evidence of asymmetries in Okun’s Law. In particular, the asymmetric Okun coefficient in the high‐growth regime turns out to be positive in several cases, implying the unemployment rate may become pro‐cyclical when actual growth rises above a certain threshold rate. 相似文献

The peer effect is a relevant issue in studies on consumption habits and consumers’ behaviour. Indeed, the extant literature shows that peers and siblings affect individual decisions and choices, as people generally follow peers’ and siblings’ examples. In other words, people imitate their peers. Starting from the existing theoretical models and empirical evidence that suggest a relevant impact of peers on one's decisions, this article analyses how the presence and the gender of siblings affects one's consumption of phone services. I consider a sample of 500 European undergraduate students. In order to isolate the peer effect, I restrict the analysis to the use of the phone for talking with friends. The results show highlight a strong sibling effect, whose magnitude and whose sign depend on both the gender of the siblings and on that of the interviewee. 相似文献

We use a Bayesian time-varying coefficient model to measurecontagion and interdependence, and we apply it to the ChileanFX market during the 2001 Argentine crisis. The proposed frameworkworks in the joint presence of heteroskedasticity and omittedvariables, without knowledge of the crisis timing prior to theempirical analysis. It can distinguish between contagion andinterdependence, as well as between unusually strong or weakmarket comovements. In a "natural" experiment based on our application,we find that the proposed framework works well in practice.In the application, we find evidence of some contagion fromArgentina and some interdependence with Brazil. 相似文献

eBusiness applications in SMEs of Italian industrial districts: the textile and wood/furniture cases
The paper presents the results of a study dealing with the adoption of eBusiness applications in two Italian industrial districts:
the textile district in Como and the wood/furniture district in the area of Brianza. These two districts are part of important
“made in Italy” industries, with a high volume of worldwide exports. The goal of the paper is to show how Internet technology
is changing the behavior of small and medium-sized enterprises (SMEs) in these two local (but with worldwide relevance) districts
and to understand how the potential benefits and constraints for SMEs pointed out in several literature contributions are
really acting in these districts.

On the Robustness of Robustness Checks of the Environmental Kuznets Curve Hypothesis 总被引:1,自引:0,他引:1
Marzio Galeotti Matteo Manera Alessandro Lanza 《Environmental and Resource Economics》2009,42(4):551-574
Since its first inception in the debate on the relationship between environment and growth in 1992, the Environmental Kuznets
Curve hypothesis (EKC hereafter) has been subject of continuous and intense scrutiny. The most recent line of investigation
criticizes the EKC hypothesis on more fundamental grounds, in that it stresses the lack of sufficient statistical testing
of the empirical relationship and questions the very existence of the notion of EKC. Attention is in particular drawn on the
stationarity properties of the series involved—per capita emissions or concentrations and per capita GDP—and, in case of presence
of unit roots, on the cointegration property that must be present for the EKC to be a well-defined concept. Only at that point
can the researcher ask whether the long-run relationship exhibits an inverted-U pattern. On the basis of panel integration
and cointegration tests for sulfur, Stern (2004) and Perman and Stern (1999, 2003) have presented evidence and forcefully
stated that the EKC hypothesis does not exist. In this paper we ask whether similar strong conclusions can be arrived at when
carrying out tests of system fractional integration and cointegration. As an example we use the controversial case of carbon
dioxide emissions. The results show that more EKCs come back into life relative to traditional integration/cointegration tests.
However, we confirm that the EKC hypothesis remains a fragile concept.
