Further evidence regarding nonlinear trend reversion of real GDP and the CPI

This paper examines whether the CPI and real GDP for the US exhibit nonlinear reversion to trend as recently concluded by Beechey and Österholm [Beechey, M. and Österholm, P., 2008. Revisiting the uncertain unit root in GDP and CPI: testing for nonlinear trend reversion. Economics Letters 100, 221-223]. The wild bootstrap is used to correct for non-normality and heteroscedasticity in a nonlinear unit root test. The use of ‘wild bootstrapped’ critical values affects test conclusions in some cases. Results also are sensitive to the sample period examined.     

Franchising and firm financial performance among U.S. restaurants

Franchising has attracted the attention of retailing and entrepreneurship scholars in the past three decades, but evidence pertaining to how franchising affects financial performance is mixed and inconclusive. Thus, the question remains as to whether franchising firms exhibit better financial performance than non-franchising firms in the same industry. In order to find an answer to this question, our study compares the risk-adjusted financial performance of franchising versus non-franchising restaurant firms over the 1995–2008 interval, using five different performance measures: the Sharpe Ratio, the Treynor Ratio, the Jensen Index, the Sortino Ratio, and the Upside Potential Ratio. For each measure, the results revealed that franchising restaurant firms outperformed their non-franchising counterparts. Thus, we provide very robust evidence that franchising is superior on average in the restaurant industry, which can help explain the increasing popularity of franchising as a business form.     

Case for Evaluating Protection in an Economy-wide Perspective

‘Whether protectionism spreads, imposing major harm on the world economy, depends on three factors: the costs and benefits of trade for domestic political actors; these actors’ access to and control over the process of government; and the extent to which international commitments and obligations to trade policy are viewed as binding by national governments’ —Costs and Benefits of Protection (Paris: OECD Secretariat, 1985)

Corporate hedging and input price risk

Input price variability is an important source of risk for corporations that process raw commodities. Models of optimal input hedging are developed in this paper based on the maximization of managerial expected utility. The relationship between hedging strategies and output decisions is examined to assess the impact of the ability to set output prices on futures market participation. As a firm's ability to set output prices diminishes in the short run, input futures positions increase although the optimal hedge ratio may either increase or decrease. For a perfectly competitive firm, however, shifts in output price caused by input price changes provide a natural cash market hedge of input price risk and reduce the firm's optimal input futures position.     

From schoolyard to workplace: The impact of bullying on sales and business employees' machiavellianism,job satisfaction,and perceived importance of an ethical issue

Bullying can precipitate many negative outcomes at work, but previous research does not adequately address how such misbehavior affects employee dispositions and attitudes; how these characteristics impact ethical decision making is also underexplored. Given these research gaps, the purpose of this study is to assess (1) the impact of bullying on Machiavellianism and job satisfaction, and (2) the influences of Machiavellianism and job satisfaction on perceived ethical issue importance, a measure of ethical decision making. Three hundred eighty‐four sales and business employees working for different firms operating in the United States answered a self‐report questionnaire. The findings showed that, after accounting for social desirability bias, workplace bullying was positively associated with Machiavellianism and negatively associated with job satisfaction. Machiavellianism was negatively related to the perceived importance of an ethical issue embedded in a vignette highlighting Machiavellianism and latent bullying behaviors. In addition, job satisfaction was positively related to ethical issue importance. Finally, both Machiavellianism and job satisfaction mediated the relationship between bullying experiences and importance of an ethical issue, as evidenced by their significant indirect effects. HR professionals should minimize bullying and Machiavellianism to reduce the corrosive effect on the ethical environment and enhance work attitudes and ethical decisions.
