This paper analyses the effects of non-performing loans (NPLs) on the cost of capital, and on lending and liquidity supply, for a sample of 225 Eurozone banks over the period 2002Q1-2016Q4. Our results demonstrate that NPLs increase the cost of capital, which reduces both lending supply and liquidity creation. This phenomenon is comparatively more significant for periphery county banks than for core country banks. 相似文献

We extract variance and skew risk premiums from volatility derivatives in a model-free way and analyze their relationships along with volatility index and equity index returns. These risk premiums can be synthesized through option trading strategies. Using a time series of option prices on the VIX, we find that variance swap excess return can be partially explained by volatility index and equity index excess returns while these latter variables carry little information for the skew swap excess return. The results sharply contrast with those obtained for the equity index option market underlining very specific characteristics of the volatility derivative market. 相似文献

Owner operator truck drivers have been dealing with a long-standing problem: compensation per distance. Owner operators who get paid according to these criteria get a fixed payment per distance traveled regardless of how long it takes to actually cover the distance. This means that there are numerous situations that truck drivers are working; yet they might be unpaid because the truck is not moving. To compensate for the unfairness of the pay rate models, owner operators have continuously increased their working hours. In addition, many studies have confirmed that a fair payment is among the most important factors that truck drivers take into consideration when deciding to leave a company. Consequently, an unfair pay rate, along with the hard labor conditions truck drivers suffer from, inevitably leads to high turnover rates. For all these reasons, our study aims at developing a fair, financially sustainable pay rate for owner operators that will help companies ensure a stable and highly experienced workforce by making sure that owner operators can cover the real expenses of their working activity. Finally, in order to prove that our pay rate was of practical use, we test the model on one of the largest Spanish agro-food companies. 相似文献

- People tend to like others with attributes similar to their own (the similarity principle) and favor products with names similar to their own (the name letter effect).
- In the present field experiment, the name letter effect and similarity principle are tested in a phonaton among alumni of Utrecht University, The Netherlands. First name and surname initials, fields of education, and association memberships of alumni were matched to those of students soliciting contributions in the phonaton.
- Female alumni with first names and fields of study similar to those of solicitors were more likely to donate, as were male alumni with first names similar to the field of study of solicitors. Both male and female alumni with first names similar to the name of the university donated more often than those with dissimilar names.
- Name letter effects are a cheap and effective instrument to increase donations in fundraising campaigns conducted by telephone.

Entrepreneurship,income distribution and economic growth 总被引:1,自引:0,他引:1

Traditionally different factors and variables have been considered in the economic growth models. Following Solow’s model,
economists considered physical capital and technology during 1950s–1980s. With the introduction of endogenous growth models,
new forms of capital were introduced in the production function; human capital, public capital and more recently social capital.
However, the consideration of qualitative variables is necessary to improve the economic growth analysis. The improvement
of statistical information has favored their introduction in the economic growth models. Recently, “entrepreneurship” concept
has been considered in this type of analysis. Entrepreneurship considers the capacity and ability to create new business and
production activity. It is an activity not an occupation. Some authors like Schumpeter have included it in their models and
they have analysed its effects on economic growth. But it is also necessary to include the role of social climate, that in
a schumpterian way it could be represented by income distribution. The main objective of the paper is to analyze the relationship
between entrepreneurship, income distribution and economic growth following the ideas developed by Schumpeter and we will
contrast them from a empirical analysis using the GEM (Global Entrepreneurship Monitor) data. 相似文献

This paper deals with the characterization problem of the minimal entropy martingale measure (MEMM) for a Markov-modulated
exponential Lévy model. This model is characterized by the presence of a background process modulating the risky asset price
movements between different regimes or market environments. This allows to stress the strong dependence of financial assets
price with structural changes in the market conditions. Our main results are obtained from the key idea of working conditionally
on the modulator-factor process. This reduces the problem to studying the simpler case of processes with independent increments.
Our work generalizes some previous works in the literature dealing with either the exponential Lévy case or the exponential-additive
case. 相似文献

We perform an experiment which provides a laboratory replica of some important features of the welfare state. In the experiment,
all individuals in a group decide whether to make a costly effort, which produces a random (independent) outcome for each
one of them. The group members then vote on whether to redistribute the resulting and commonly known total sum of earnings
equally amongst themselves. This game has two equilibria, if played once. In one of them, all players make effort and there
is little redistribution. In the other one, there is no effort and nothing to redistribute. A solution to the repeated game
allows for redistribution and high effort, sustained by the threat to revert to the worst of these equilibria. Our results
show that redistribution with high effort is not sustainable. The main reason for the absence of redistribution is that rich
agents do not act differently depending on whether the poor have worked hard or not. The equilibrium in which redistribution
may be sustained by the threat of punishing the poor if they do not exert effort is not observed in the experiment. Thus,
the explanation of the behavior of the subjects lies in Hobbes, not in Rousseau. 相似文献

In this paper, we introduce a new class of models for the time evolution of the prices of call options of all strikes and
maturities. We capture the information contained in the option prices in the density of some time-inhomogeneous Lévy measure
(an alternative to the implied volatility surface), and we set this static code-book in motion by means of stochastic dynamics
of It?’s type in a function space, creating what we call a tangent Lévy model. We then provide the consistency conditions, namely, we show that the call prices produced by a given dynamic code-book (dynamic Lévy density) coincide with the conditional expectations of the respective payoffs if and only if certain restrictions on the dynamics
of the code-book are satisfied (including a drift condition à la HJM). We then provide an existence result, which allows us
to construct a large class of tangent Lévy models, and describe a specific example for the sake of illustration. 相似文献

How Does the Market Value Corporate Sustainability Performance? 总被引:1,自引:0,他引:1

This study provides empirical evidence on how corporate sustainability performance (CSP), as proxied by membership of the Dow Jones sustainability index, is reflected in the market value of equity. Using a theoretical framework combining institutional perspectives, stakeholder theory, and resource-based perspectives, we develop a set of hypotheses that relate the market value of equity to CSP. For a sample of North American firms, our preliminary results show that CSP has significant explanatory power for stock prices over the traditional summary accounting measures such as earnings and book value of equity. However, further analyses suggest that we should not focus on corporate sustainability itself. Our findings suggest that what investors really do is to penalize large profitable firms with low level of CSP. Firms with incentives to develop a high level of CSP not engaging on such strategy are, thus, penalized by the market. 相似文献
