Price discovery and volatility spillovers in index futures markets: Some evidence from Mexico

This paper investigates the hypotheses that the recently established Mexican stock index futures market effectively serves the price discovery function, and that the introduction of futures trading has provoked volatility in the underlying spot market. We test both hypotheses simultaneously with daily data from Mexico in the context of a modified EGARCH model that also incorporates possible cointegration between the futures and spot markets. The evidence supports both hypotheses, suggesting that the futures market in Mexico is a useful price discovery vehicle, although futures trading has also been a source of instability for the spot market. Several managerial implications are derived and discussed.     

Factors Influencing Interest Rates on Delinquent Property Tax Certificates

This study examines the market for delinquent property tax certificates, a commonly used enforcement mechanism in property tax systems around the United States. We model the value of such certificates using a continuous-time framework and propose a statistical model that allows testing for factors that affect interest rates charged by investors who purchase the certificates as investment instruments. Using sample data from tax certificate sales in Florida from 1982 to 2000, we find that interest rates on certificates are negatively and significantly related to assessed property value and homestead status, and positively related to local ownership. We find an inverse relationship between interest rates and the number of certificates purchased by the certificate investor, indicating a significant clientele effect in this market. We also find that the implied effective tax rate is positively related to the interest rates charged by investors. Overall, the findings provide insight into the function of this unique market niche.     

Impact of mass customization on cost and flexiblity performances: the role of social capital

More than ever, companies have to cope with ever changing market conditions. Some companies have reacted to shortened product life cycles, constant changes in customer preferences and cost pressures by implementing mass customization practices. Mass customization has been hailed as a way to overcome the tradeoff between cost and flexibility performance. However, there is lack of consistent empirical evidence to demonstrate that this really is the case. We advance this debate by proposing that in order for mass customization to be more effective, a company needs to possess and utilize social capital (i.e., cognitive, relational and structured social capital) within their supply networks. This study uses primary survey data from 513 plants from nine countries collected by the Global Manufacturing Research Group (GMRG). We used structural equation modelling analysis to test our hypotheses. Results indicate that mass customization has the ability to improve a company’s cost and flexibility performance. Furthermore, results regarding the moderating role of social capital are mixed. Cognitive capital only moderates the impact of mass customization on cost performance while relational capital increases this impact on both cost and flexibility performance. Structural capital does not moderate the impact of mass customization on performance.     

Modelling generalized firms’ restructuring using inverse DEA

The key consideration for firms’ restructuring is improving their operational efficiencies. Market conditions often offer opportunities or generate threats that can be handled by restructuring scenarios through consolidation, to create synergy, or through split, to create reverse synergy. A generalized restructuring refers to a move in a business market where a homogeneous set of firms, a set of pre-restructuring decision making units (DMUs), proceed with a restructuring to produce a new set of post-restructuring entities in the same market to realize efficiency targets. This paper aims to develop a novel inverse Data Envelopment Analysis based methodology, called GInvDEA (Generalized Inverse DEA), for modeling the generalized restructuring. Moreover, the paper suggests a linear programming model that allows determining the lowest performance levels, measured by efficiency that can be achieved through a given generalized restructuring. An application in banking operations illustrates the theory developed in the paper.     

Mortgage Loan Rates and Deposit Costs: Are They Reliably Linked?

The deposit-cost markup theory of Jaffe and Rosens type suggests that the cost of attracting funds determines prices (mortgage loan rates). Other equally plausible theories argue for the reverse chain of events, whereby mortgage loan rates induce changes in the deposit interest rates. We investigate these alternative hypotheses over the monthly period 1970 to 1994 using causality and cointegration tests with allowances for possible structural breaks. The results from error-correction models indicate the presence of bidirectional causality between the mortgage loan rates and the deposit interest rates. The results further show that the two variables exhibit a strong cointegrating relationship and that several factors play an important role in determining both variables. Our findings underscore the need to continue with efforts to develop and test multivariate error-correction models for the joint determination of the mortgage loan rate and the deposit interest rate.

The role of electronic word of mouth,conventional media,and subjective norms on the intention to purchase <Emphasis Type="Italic">Sharia</Emphasis> insurance services

The aim of this study was to investigate the effect of electronic word of mouth (eWOM) and conventional media on subjective norms and intention to purchase Sharia insurance in Indonesian Muslim society. The research data consisted of 458 Muslim clients who were members of an online community and also policy holders of Sharia insurance in the three largest cities in Indonesia: Jakarta, Semarang, and Surabaya. This study used purposive sampling and structural equation modeling. The research showed that eWOM and conventional media can affect subjective norms. Additionally, subjective norms have a significant effect on the intention to purchase among Sharia insurance customers. This study validated the importance of the variables of eWOM and conventional media in influencing subjective norms and intention to purchase. For Sharia insurance company management, this study can serve as a very useful reference in drafting and formulating campaign strategies. This study also justifies the integrated relationship between eWOM and conventional media with subjective norms and intention to purchase Sharia insurance.     

Fuel Intensity,Access to Finance and Profitability: Firm-Level Evidence from China

Sustainability and energy economics together as a field has rapidly developed in recent years. However, it is still limited of the literature regarding the effect of energy on firm performance. This article fills the gap by providing empirical evidence from China on the fuel intensity-performance link at the firm level. Our findings are summarized as follows: (i) firms’ fuel intensity significantly constrains the firms’ profitability and the constraint effect is significantly greater for firms with no access to finance; (ii) an increase in fuel intensity reduces profitability by intensifying the financial constraint effect; and (iii) financial access moderates the constraint effect of fuel intensity on firm’s performance. The policy implications of the findings are discussed.     

Terror attacks and stock-market fluctuations: evidence based on a nonparametric causality-in-quantiles test for the G7 countries

We use a novel nonparametric causality-in-quantiles test to study the effects of terror attacks on stock-market returns and volatility in G7 countries. We also use the novel test to study the international repercussions of terror attacks. Test results show that terror attacks often have significant effects on returns, whereas the effect on volatility is significant only for Japan and the UK for several quantiles above the median. The effects on returns in many cases become stronger in terms of significance for the upper and lower quantiles of the conditional distribution of stock-market returns. As for international repercussions, we find that terror attacks mainly affect the tails of the conditional distribution of stock-market returns. We find no evidence of a significant cross-border effects of terror attacks on stock-market volatility, where again Japan and the UK are exceptions as far as terror attacks on the US are concerned. Finally, our results continue to hold following various robustness checks involving model structure, lag-lengths and possible omitted variable bias.     

Time-varying managerial overconfidence and corporate debt maturity structure

We examine the impact of managerial overconfidence on corporate debt maturity. We build upon the argument that managerial overconfidence is likely to mitigate the underinvestment problem, which is often the major concern for long-term debt investors. Within this context, we hypothesise that managerial overconfidence increases debt maturity. Our empirical evidence, based on time-varying measures of overconfidence derived from computational linguistic analysis and directors’ dealings in their own companies’ shares, supports this hypothesis. Specifically, we find that the changes in both first person singular pronouns and optimistic tone are positively related to the change in debt maturity. Moreover, we find that the insider trading-based overconfidence of CEO, who is most likely to influence investment decision and thus the underinvestment problem, has a stronger impact on debt maturity than the overconfidence of other directors (e.g. CFO). Overall, our study provides initial evidence for a positive overconfidence-debt maturity relation via overconfidence mitigating the agency cost of long-term debt.
