This article examines the effects of excess capacity on the production cost and technical inefficiency of hotels and restaurants in Norway. The dataset includes a daily unbalanced panel of 94 hotels and restaurants from 2003 to 2014. To accommodate inefficiency, we use an input distance function (IDF). Inefficiency in the IDF means that if inputs are overused by k% then production cost is also increased by k%. We also allow inefficiency to differ across locations and regions by using them as determinants. The results indicate that excess capacity considerably affects the cost and increases inefficiency. The marginal effect on cost increases with excess capacity, but the effect on inefficiency sets in when it exceeds 50 percent. Furthermore, we find less overuse of inputs by firms in small metro towns and the Northern region causing them to be more efficient [except for the Southern and Western regions] than their counterparts.  相似文献

基于竞争理论的国企改革思路强调减少政策性负担摊派,基于产权理论的改革思路侧重于引入非国有资本,以解决产权不清晰与所有者缺位问题.本文尝试融合两种理论,以国企超额雇员问题为研究对象,从非国有大股东视角探究混合所有制改革成效.研究发现:非国有大股东能够显著降低国企超额雇员,减弱超额雇员对公司价值的损害作用,且该治理作用会随非国有大股东相对力量的提高而增强;从作用机制来看,该治理作用不仅表现为劳动力成本尤其是员工薪酬的节约,还表现为内部薪酬差距和管理层薪酬业绩敏感性的提高,兼具成本效应与激励效应;该作用在地区就业压力较小、劳动密集度较低以及劳动保护水平更低的环境下更为显著.  相似文献

It has been claimed that, for dynamic investment strategies, the simple act of rebalancing a portfolio can be a source of additional performance, sometimes referred to as the volatility pumping effect or the diversification bonus because volatility and diversification turn out to be key drivers of the portfolio performance. Stochastic portfolio theory suggests that the portfolio excess growth rate, defined as the difference between the portfolio expected growth rate and the weighted-average expected growth rate of the assets in the portfolio, is an important component of this additional performance (see Fernholz [Stochastic Portfolio Theory, 2002 (Springer)]). In this context, one might wonder whether maximizing a portfolio excess growth rate would lead to an improvement in the portfolio performance or risk-adjusted performance. This paper provides a thorough empirical analysis of the maximization of an equity portfolio excess growth rate in a portfolio construction context for individual stocks. In out-of-sample empirical tests conducted on individual stocks from 4 different regions (US, UK, Eurozone and Japan), we find that portfolios that maximize the excess growth rate are characterized by a strong negative exposure to the low volatility factor and a higher than 1 exposure to the market factor, implying that such portfolios are attractive alternatives to competing smart portfolios in markets where the low volatility anomaly does not hold (e.g. in the UK, or in rising interest rate scenarios) or in bull market environments.  相似文献

作为企业治理的重要问题之一,代理成本诱发超额在职消费引起各界广泛关注。文章以2007-2019年A股上市公司为初始样本,考察我国各省社会资本水平差异对超额在职消费影响。研究表明,社会资本显著提高超额在职消费,起到推波助澜的负面效用;进一步研究表明,公司治理水平维度上通过提高机构投资持股比例、短期债务融资比例及扩大独立董事比例和监事会规模均能抑制社会资本加剧超额在职消费的负面效用,公司治理环境维度上通过强化企业内部治理环境、加快市场化进程亦能削弱社会资本对超额在职消费的“推波助澜”。以上结论为社会资本利弊之争提供有益补充,亦凸显非正式制度与正式制度的治理替代效应,同时为企业完善内部治理水平及政府优化制度环境与规则治理以抑制社会资本负面效用提供一定借鉴。  相似文献

This article analyses the effects of involuntary excess reserves (IER) on bankers’ remuneration and the penalty associated with bank risk-taking if discovered. The study finds that IER help conceal tail risks, improves bankers’ performance and remuneration. However, the risks once discovered result in heavy penalties on bankers’ remuneration. The study extends the agency theory to the context where banks hold large IER.  相似文献

This paper examines the stability of money demand and the forecasting performances of a broad monetary aggregate (M3), excess liquidity and excess inflation in predicting euro area inflation. The out-of sample forecasting performances are compared to a widely used alternative, the spread of interest rates. The results indicate that the evolution of M3 is still in line with money demand, even when observations from the economic and financial crisis are included. Both excess measures and the spread are useful for predicting inflation.  相似文献

本文选取2010—2016年中国沪深A股上市公司样本,实证检验CEO学术经历对高管在职消费行为的影响。研究发现,学术经历有助于CEO强化道德自觉、增强道德自律,形成内在的自我约束与监督机制,进而抑制了其所在企业的高管在职消费活动。当CEO拥有高层次学术经历或来自内部晋升时,CEO学术经历对高管在职消费的抑制效应更为显著。该结论在采用双重差分模型、Heckman两阶段模型控制潜在的内生性问题及其他稳健性检验之后仍然成立。进一步研究表明,在自由现金流较多、董事会规模较大或独立性较低、外部审计监督较弱以及产品市场竞争程度较低等公司内外部治理环境较差的情景下,学者型CEO的自律品质所能发挥的治理作用更大,对高管在职消费的抑制效应也更为明显。此外,在党的十八大之后,随着“八项规定”等多项高压反腐政策的出台,政策效应在国有企业高管在职消费的治理中发挥着主导性作用,CEO学术经历对国有企业高管在职消费的抑制效应有所下降。本文为高管学术经历的治理效应假说提供了证据支持,对于上市公司规范和治理高管在职消费行为、选聘合适的高管人才具有重要的借鉴意义。  相似文献

近年来,我国互联网金融蓬勃发展。面对各种互联网金融业态争相涌现,政府采取了较为积极的态度,但在2014年“两会”后则加强了对互联网金融发展的监管,以防范金融风险,维护金融安全。本文从政治经济学的角度来分析互联网金融的监管问题,指出如果放任互联网巨头开展互联网金融,可能会导致互联网超额利润和金融超额利润的叠加,从而引起新的社会不公。因此,政府需要加强对互联网金融的监管,鼓励有序竞争,促进互联网金融的健康发展。  相似文献

The excessive volatility of prices in financial markets is one of the most pressing puzzles in social science. It has led many to question economic theory, which attributes beneficial effects to markets in the allocation of risks and the aggregation of information. In exploring its causes, we investigated to what extent excessive volatility can be observed at the individual level. Economists claim that securities prices are forecasts of future outcomes. Here, we report on a simple experiment in which participants were rewarded to make the most accurate possible forecast of a canonical financial time series. We discovered excessive volatility in individual-level forecasts, paralleling the finding at the market level. Assuming that participants updated their beliefs based on reinforcement learning, we show that excess volatility emerged because of a combination of three factors. First, we found that submitted forecasts were noisy perturbations of participants’ revealed beliefs. Second, beliefs were updated using a prediction error based on submitted forecast rather than revealed past beliefs. Third, in updating beliefs, participants maladaptively decreased learning speed with prediction risk. Our results reveal formerly undocumented features in individual-level forecasting that may be critical to understand the inherent instability of financial markets and inform regulatory policy.  相似文献

In this paper, we introduce a new Bayesian approach to explain some market anomalies during financial crises and subsequent recovery. We assume that the earnings shock of an asset follows a random walk model with and without drift to incorporate the impact of financial crises. We further assume the earning shock follows an exponential family distribution to accommodate symmetric as well as asymmetric information. By using this model setting, we develop some properties on the expected earnings shock and its volatility, and establish properties of investor behavior on the stock price and its volatility during financial crises and the subsequent recovery. Thereafter, we develop properties to explain excess volatility, short-term underreaction, long-term overreaction, and their magnitude effects during financial crises and the subsequent recovery. We also explain why behavioral finance theory could be used to explain many of the asset pricing anomalies, but traditional asset pricing models cannot achieve this aim.  相似文献
