Momentum,market states and investor behavior

This paper shows that the momentum effect appears in the wake of both up-market and down-market states in the Spanish stock market, although in the first of these cases it is followed by return reversal. This evidence, which contradicts the predictions of Cooper et al. (2004), provides the rationale for taking into account the disposition effect among the possible explanatory factors behind the momentum effect in a behavioral theory context.      

Promote or Perish? A brief note on academic social networking sites and academic reputation

ABSTRACT

This commentary explores some of the reputational issues of using academic social networking sites (ASNS) such as ResearchGate, ResearcherID, ORCID, Academia.edu, Google Scholar, and Mendeley for academic self-promotion and considers whether the adage of ‘Publish or Perish’ has been recently overshadowed by the new imperative of ‘Promote or Perish’?     

How do extended benefits affect unemployment duration? A regression discontinuity approach

This paper studies a targeted program that extends the maximum duration of unemployment benefits from 30 weeks to 209 weeks in Austria. Sharp discontinuities in treatment assignment at age 50 and at the border between eligible regions and control regions identify the effect of extended benefits on unemployment duration. Results indicate that the duration of job search is prolonged by at least 0.09 weeks per additional week of benefits among men, whereas unemployment duration increases by at least 0.32 weeks per additional week of benefits for women. This finding is consistent with a lower early retirement age applying to women.     

An Empirical Assessment of the Contract Based Exception to the Employment-At-Will Rule

While extensive, the existing literature on the employment-at-will doctrine and its various exceptions has been remarkably uniform. By relying on a discussion of selected court opinions on specific aspects of the doctrine, scholars have focused primarily on normative issues such as what the courts should do when deciding job security disputes, or what plaintiffs/employees and defendants/employers should argue when litigating employment disputes. Our approach and focus are different. Instead of relying on a discussion of selected cases, we rely on a more comprehensive sample of cases. Instead of focusing on normative issues, our goal is to provide a more complete picture of the state of the at-will doctrine as reflected in those cases. Our data should be of interest to legal scholars interested in understanding the characteristics and outcomes of litigated employment-at-will cases. Our data should also be relevant to the current debate among management scholars regarding conflicts that might arise due to aggressive recruitment practices which highlight long term employment opportunities and the realities associated with at-will employment.     

Pricing equity default swaps under the jump-to-default extended CEV model

Equity default swaps (EDS) are hybrid credit-equity products that provide a bridge from credit default swaps (CDS) to equity derivatives with barriers. This paper develops an analytical solution to the EDS pricing problem under the jump-to-default extended constant elasticity of variance model (JDCEV) of Carr and Linetsky. Mathematically, we obtain an analytical solution to the first passage time problem for the JDCEV diffusion process with killing. In particular, we obtain analytical results for the present values of the protection payoff at the triggering event, periodic premium payments up to the triggering event, and the interest accrued from the previous periodic premium payment up to the triggering event, and we determine arbitrage-free equity default swap rates and compare them with CDS rates. Generally, the EDS rate is strictly greater than the corresponding CDS rate. However, when the triggering barrier is set to be a low percentage of the initial stock price and the volatility of the underlying firm’s stock price is moderate, the EDS and CDS rates are quite close. Given the current movement to list CDS contracts on organized derivatives exchanges to alleviate the problems with the counterparty risk and the opacity of over-the-counter CDS trading, we argue that EDS contracts with low triggering barriers may prove to be an interesting alternative to CDS contracts, offering some advantages due to the unambiguity, and transparency of the triggering event based on the observable stock price.     

Herd Behavior in Latin American Stock Markets

ABSTRACT

This article investigates the presence of herd behavior in Latin American stock markets using the methodologies proposed by Christie and Huang (1995 Christie , W. G. , &; Huang , R. D. ( 1995 ). Following the pied piper: Do individual returns herd around the market? Financial Analysts Journal , 51 ( 4 ), 31 – 37 .[Taylor &; Francis Online] , [Google Scholar]) and Chang, Cheng, and Khorana (2000 Chang , E. C. , Cheng , J. W. , &; Khorana , A. ( 2000 ). An examination of herd behavior in equity markets: An international perspective . Journal of Banking and Finance , 24 ( 10 ), 1651 – 1679 .[Crossref], [Web of Science ®] , [Google Scholar]). Daily closing prices and trading volumes from January 3, 2000 to September 15, 2010 from the stock markets of Argentina, Brazil, Chile, Mexico, and the United States were analyzed. The US market was studied in order to provide a reference for comparison. The shares for which data was collected in each country were those listed in the most representative stock index for each market. It was not possible to establish evidence of herd behavior in any of the five countries studied using the Christie and Huang (1995 Christie , W. G. , &; Huang , R. D. ( 1995 ). Following the pied piper: Do individual returns herd around the market? Financial Analysts Journal , 51 ( 4 ), 31 – 37 .[Taylor &; Francis Online] , [Google Scholar]) method. However, evaluating the data for the entire period using the method proposed by Chang, Cheng, and Khorana (2000 Chang , E. C. , Cheng , J. W. , &; Khorana , A. ( 2000 ). An examination of herd behavior in equity markets: An international perspective . Journal of Banking and Finance , 24 ( 10 ), 1651 – 1679 .[Crossref], [Web of Science ®] , [Google Scholar]) we detected herd behavior in the Chilean market. These results were not affected by the addition of additional exogenous variables representing the September 11 attacks of 2001 and the subprime crisis, or when the effect of the behavior of US shares on other countries was analyzed. Asymmetric herd behavior was detected in the Chilean, United States, Argentinean, and Mexican markets.     

The role of small bettors in price formation in betting exchanges

ABSTRACT

The presence of small bettors in betting exchanges generates mispricing, which can lead to exploitation by informed traders or result in permanent price deviations. This paper shows that mispricing from this source is also dependent upon variables of established relevance such as tournament round, the level of attention to the event, the volume of the betting, and bet type, further confirming these findings by means of cumulative accuracy profile (CAP) curves. It also offers evidence of the relevant role played by the type of device used to place the bet, whereby higher mispricing is observed in live bets placed via a mobile device, which appears to be associated with impulsive betting. This last finding could have practical implications for the regulation of the use of mobile devices to access gambling platforms.     

Automated Certification for Compliant Cloud-based Business Processes

A key problem in the deployment of large-scale, reliable cloud computing concerns the difficulty to certify the compliance of business processes operating in the cloud. Standard audit procedures such as SAS-70 and SAS-117 are hard to conduct for cloud-based processes. The paper proposes a novel approach to certify the compliance of business processes with regulatory requirements. The approach translates process models into their corresponding Petri net representations and checks them against requirements also expressed in this formalism. Being based on Petri nets, the approach provides well-founded evidence on adherence and, in case of noncompliance, indicates the possible vulnerabilities.     

Functional dependence and productive dependence of SMEs

This article analyzes the quality of business structure from a macroeconomic perspective in the regional context. In addition to “traditional” variables such as innovation, internationalization, or entrepreneurial collaboration, new variables have been introduced: functional dependence and productive dependence. Two different economic territories have been chosen within the Spanish economy: the province of Barcelona (high relative income per capita) and the province of Seville (low relative income per capita). We find it is possible to distinguish two types of firms: a) “product-maker” firms (mainly located in advanced areas) and b) “market-maker” firms (mainly located in less developed areas).      

Export Growth and Economic Development in Colonial British America

This paper analyzes the dynamic relationship between tobacco and the rest of the economy in the colonial Chesapeake to test the staple theory version of the export-led growth hypothesis. The paper adopts a multivariate time-series approach which accommodates the presence of cointegration and contemporaneous correlations among innovations. The empirical evidence strongly supports the staple theory. British demand for tobacco is statistically exogenous and found to induce cyclical fluctuations in the colonial price of tobacco as well as temporary over- or underproduction, as measured by a long-term cointegration relationship between the British demand for tobacco and the colonial price of land.
