We develop a novel contract design, the fed funds futures (FFF) variance futures, which reflects the expected realized basis point variance of an underlying FFF rate. The valuation of short-term FFF variance futures is completely model-independent in a general setting that includes the cases where the underlying FFF rate exhibits jumps and where the realized variance is computed by sampling the FFF rate discretely. The valuation of longer-term FFF variance futures is subject to an approximation error which we quantify and show is negligible. We also provide an illustrative example of the practical valuation and use of the FFF variance futures contract. 相似文献

The aim of the research was to determine consumer perceptions of meat products regarding their origin and the potential impact of their origin on the sensory evaluation of other meat properties. Data were collected during the experiment. By testing the correlation model with multiple analyses of variance for repeated measures, it was determined that there was a statistically significant correlation between the factors. The important contribution of the research is the surveyed issue and the approach to researching the impact of product origin on scientific field of marketing and field of consumer behavior. The research represents a deeper investigation of impact of country-of-origin (COO) on consumer perceptions. An integrated approach to the research of the impact of meat origin was chosen to form interlinks between meat origin and its other sensorical properties. 相似文献

Using a rich panel dataset of small and medium scale manufacturing enterprises (SMEs) active in the manufacturing sector in Viet Nam, this paper investigates the drivers of firm productivity, focusing on the role played by international management standards certification. We test the hypothesis that, accounting for technological innovation (product and process) and other variables related to technological capabilities, international standards are conducive to higher productivity, through improved management practices and business organization. In line with the requirement of continuous improvement implied by most international standards, the main findings show that the possession of an internationally recognized standard certificate leads to significant productivity premium. We further find that the effect of certification on productivity is particularly strong for firms with technological innovation, located in southern provinces, and operating in more scale-intensive industries. 相似文献

Normally, privatisation is seen as beneficial. This paper considers the case of Serbia – a latecomer in the matter – where privatisation was partly a result of exogenous pressures and where the process has been deemed a failure. In Serbia, a sizeable number of privatised firms were bought by bureaucrats and politicians and all firms were subjected to a period of supervision. We argue that the design of this process allowed rent-seekers to conserve their privileges through asset-stripping, which explains the failure. In order to do so, we perform an empirical analysis of the determinants of liquidation, merger and bankruptcy of privatised firms from 2002 to 2015. We construct a novel data set from primary sources, free of the ‘survivorship bias’ and containing proxies for various types of owners, indirect signs of asset-stripping strategy and a broad range of controls. Our results indicate that firms owned by politicians faced significantly higher risks of bankruptcy, especially after the end of supervision. 相似文献

In this article we survey methods of dealing with the following problem: A financial agent is trying to hedge a claim C, without
having enough initial capital to perform a perfect (super) replication. In particular, we describe results for minimizing
the expected loss of hedging the claim C both in complete and incomplete continuous-time financial market models, and for
maximizing the probability of perfect hedge in complete markets and markets with partial information. In these cases, the
optimal strategy is in the form of a binary option on C, depending on the Radon-Nikodym derivative of the equivalent martingale
measure which is optimal for a corresponding dual problem. We also present results on dynamic measures for the risk associated
with the liability C, defined as the supremum over different scenarios of the minimal expected loss of hedging C.

Testing for Bubbles in Housing Markets: A Panel Data Approach 总被引:3,自引:0,他引:3
We employ recently developed cross-sectionally robust panel data tests for unit roots and cointegration to find whether house prices reflect house related earnings. We use U.S. data for Metropolitan
Statistical Areas, with house price measured by the weighted-repeated-sales index and cash-flows by market tenants’ rents.
In our full sample period, an error-correction model is not appropriate, i.e. there is a bubble. We then combine overlapping
10-year periods, price–rent ratios, and the panel data tests to construct a bubble indicator. The indicator is high for the
late 1980s, early 1990s and since the late 1990s. Finally, evidence based on panel data Granger causality tests suggests that
house price changes are helpful in predicting changes in rents and vice versa.

Using daily data the Cagan money demand is estimated and accepted for the most severe portion of Serbia’s 1992–1993 hyperinflation, i.e. its last 6 months. An implication is that the public adjusted daily throughout this extreme period. Moreover, the obtained semi-elasticity estimates are by far lower than those previously found using monthly data sets. Consequently, the daily estimates reject the longstanding Cagan’s paradox, based on monthly studies, by showing that the economy has been on the correct, increasing side of the Laffer curve almost through the end of hyperinflation. This strongly supports the view that hyperinflation is triggered and driven all way through its end by the government’s hunt for non-decreasing seigniorage. Daily adjustments of public in hyperinflation can account for the difference between the results obtained at daily and monthly frequencies, calling into question the latter. Some evidence is offered that the findings of this paper may hold for other hyperinflations. 相似文献

The Skaraborg Hospital Group (SkaS) has implemented a variety of quality management initiatives in the last 20 years in accordance with its strategy of excelling at quality development to fulfill the needs and expectations of its patients. One such initiative is Six Sigma, which has contributed to more than 40 completed improvement projects. Using an action research approach, this article describes the lessons that were learned from the first 22 Six Sigma projects, completed between 2006 and 2008 and having a success rate of 75%. We further describe how these insights have contributed to other ongoing quality improvement activities at SkaS. In particular, the paper presents some key points not earlier described in other Six Sigma healthcare applications. 相似文献

Given the high risk of severe accidents at level crossings (LCs), this study examined legal and illegal crossings by pedestrians and cyclists at a high-traffic LC in Zagreb, Croatia. Survey data and field observations were collected to identify reasons for risky behaviour. Behaviour was observed under normal conditions and in the presence of various safety measures in order to identify measures that can reduce risky behaviour. Results show that the presence of police officer at the LC was most effective at reducing illegal crossings, while the presence of cameras contributes significantly as well, especially after safety educational campaign when illegal crossing decreases for 59.23%. We can assume that in future the improvement regarding human behaviour on LC could be made with cameras on LC and more frequent educational campaigns. This is the first reported use of field survey and video surveillance methods to analyse user behaviour at LCs in Croatia. 相似文献
