Innovation and Exporting: Does Quality Matter?

We study the effect of innovation on a firm’s propensity to export, developing a simple model where heterogeneous firms operate in a monopolistically competitive market and set their prices as a markup above the marginal cost. The key proposition of our model is that firms that invest in better quality products are more likely to export. We test it using Italian firms’ data. Econometric results suggest that innovation, defined as quality upgrading, has a significant effect on the firms’ propensity to export; and, for those who are already exporting, innovation—defined as new products—has a significant effect on a firm’s turnover.     

Exploring Different Types of Sharing: A Proposed Segmentation of the Market for “Sharing” Businesses

Sharing instead of buying is regaining traction among today's consumers. This study aims at identifying segments of sharing consumers to unearth potentially viable clusters of a consumer behavior that is a market of growing economic relevance. By means of a qualitative study and a survey with a roughly representative sample of 1121 Swiss‐German and German consumers, a set of trait‐related, motivational, and perceived socioeconomic variables is identified that can be used to group individuals into segments that differ with regard to their approach to sharing. A cluster analysis based on these variables suggests four potential clusters of sharing consumers—sharing idealists, sharing opponents, sharing pragmatists, and sharing normatives. Two sets of testable propositions are derived that can guide further research in this domain and pave the way to a more targeted approach to the growing market of “sharing” businesses.     

Effects of communication and financial concerns on banking attitude-behaviour relations

Despite extensive discussion of the concept of Islamic banking, which is based on the fundamental doctrines of Islamic law (Shariah) and Islamic economics (prohibition of interest and profit-loss sharing), few studies have explored the factors that potentially affect behaviour intentions among customers. This study investigates direct and moderating effects of communication and financial factors on customer attitudes and behavioural intentions towards Islamic banking. Data were collected from the customers of Islamic banks and the Islamic banking divisions of conventional banks in Malaysia using online surveys. The hypotheses were tested using hierarchical regression analysis. The results suggest that relationship marketing, informative advertising, perceived benefits, and profit-loss sharing are important determinants of behavioural intentions among both Muslim and non-Muslim customer groups. This study also found moderating effects for most of the conceptualized moderating variables, particularly attitude interactions with informative advertising, ease of online banking, and the principle of profit-loss sharing. There are both notable similarities and differences in the results for the two customer groups. The findings imply that different strategies should be used both to retain existing customers and attract new ones.     

Islamic corporate financing: does it promote profit and loss sharing?

Islamic financing instruments can be categorised into profit and loss/risk sharing and non‐participatory instruments. Although profit and loss sharing instruments such as musharakah are widely accepted as the ideal form of Islamic financing, prior studies suggest that alternative instruments such as murabahah are preferred by Islamic banks. Nevertheless, prior studies did not explore factors that influence the use of Islamic financing among non‐financial firms. Our study fills this gap and contributes new knowledge in several ways. First, we find no evidence of widespread use of Islamic financing instruments across non‐financial firms. This is because the instruments are mostly used by less profitable firms with higher leverage (i.e. risky firms). Second, we find that profit and loss sharing instruments are hardly used, whilst the use of murabahah is dominant. Consistent with the prediction of moral‐hazard‐risk avoidance theory, further analysis suggests that users with a lower asset base (to serve as collateral) are associated with murabahah financing. Third, we present a critical discourse on the contentious nature of murabahah as practised. The economic significance and ethical issues associated with murabahah as practised should trigger serious efforts to steer Islamic corporate financing towards risk‐sharing more than the controversial rent‐seeking practice.     

Islamic legal methodologies and Shariah screening standards: Application in the Indonesian stock market

This article provides a framework for applying the principles of Islamic legal methodology to determine the optimal Shariah screening standards for Islamic equity markets. It is argued that using maslahah mursalah (unrestricted benefit) is an appropriate method for identifying appropriate financial standards and its principles stipulate that the benchmark that yields the best economic returns to investors should be chosen. The methodological framework is applied to the Indonesia equity market where the economic implications of the Islamic stock screening standards of the Indonesian Islamic Shariah Stock Index and four global indices are assessed. Portfolios are constructed by applying Islamic stock screening standards for each of the indices by using data on 377 stocks listed in the Indonesian stock market for 5 years. The performances measured by the Sharpe ratio, Treynor index, and Jensen alpha reveal that the Dow Jones Islamic Index screening criteria performs the best. Based on the method of maslahah mursalah, the article recommends using the screening standard of this index in the Indonesian stock market to maximize benefits to investors. While the approach used in this article is applied to Islamic equity markets, the methodological framework can also be used for other similar cases in Islamic finance.     

Good governance,innovation, economic growth and the stock market turnover rate

This study is primarily aimed at testing the theory of good governance in the group of eight developing Islamic countries. Using a panel data regression model, we examined the data to determine the relationship between political economy and economic development of eight countries, for the period 2005 to 2014. The results show a significant positive correlation between the rule of law, corruption control with economic growth and stock market turnover rate proxy. The examination through an artificial neural network resulted in a higher determination coefficient and less average standard error. This, in turn, reveals that the fitting power and efficiency of this method is higher than the panel data regression model. Furthermore, the findings of this study suggest that the application of good governance theory calls for more inquiry.     

A Leland model for delta hedging in central risk books

Using a tractable extension of the model of Leland (1985), we study how a delta-hedging strategy can realistically be implemented using market and limit orders in a centralized, automated market-making desk that integrates trading and liquidity provision for both options and their underlyings. In the continuous-time limit, the optimal limit-order exposure can be computed explicitly by a pointwise maximization. It is determined by the relative magnitudes of adverse selection, bid–ask spreads, and volatilities. The corresponding option price—from which the option can be replicated using market and limit orders—is characterized via a nonlinear PDE. Our results highlight the benefit of tactical liquidity provision for contrarian trading strategies, even for a trading desk that is not a competitive market maker. More generally, the paper also showcases how reduced-form models are competitive with “brute force” numerical approaches to market microstructure. Both the estimation of microstructure parameters and the simulation of the optimal trading strategy are made concrete and reconciled with real-life high frequency data.     

Firms’ internationalization and alternative approaches to the international customer/market selection

While the theoretical development and empirical studies on exchange transaction modality to international markets have been impressing, relatively few researchers have focused on the process by which firms select where or with whom the transactions should be performed. This paper is an attempt to establish a research agenda on the selection of foreign market or customer. The characteristics of the ‘traditional’ approaches—systematic and non-systematic—are examined and compared with a relationship approach. Furthermore, this paper emphasizes the interrelationship between the choice of entry mode and choice of foreign market/customer. The authors develop research propositions suggesting circumstances under which a relationship approach is more likely than a traditional approach. Future research directions are illuminated.     

The adverse selection cost component of the spread of Brazilian stocks

This study analyzes the adverse selection cost component embedded in the spreads of Brazilian stocks. We show that it is higher than in the U.S. market and presents an intraday U-shape pattern (i.e., higher at the beginning and at the end of the day). In addition, we investigate the relationships of the adverse selection cost with a firm's characteristics. We find that stocks listed in the highest corporate governance levels do not have the lowest costs. On the other hand, the liquidity of shares, the trade size and the market value of the firm are directly correlated with this cost.

Western Financial Agents and Islamic Ethics

This paper investigates Western professional bankers’ perceptions of Islamic finance. Exploiting data from an original survey, we carry out a principal component analysis (PCA) to characterize the main dimensions on which financial agents diverge. The PCA extracts five dimensions—accounting for 61 % of the variance in the agents’ answers—that we interpret with the help of a pilot field survey. In addition to confirm the increased association of Islamic financial values with ethical practices in the West, our results allow us to understand how the observed growth of the industry has been conceptualized by conventional agents. The five dimensions identified shed light on the multitude of constructs that have informed the diffusion of Islamic financial ideas to international markets. This supports the fact that Islamic finance cannot be seen as a single movement but is characterized by opposing and concurrent logics in global markets.     

From “Lemons” to Lemonade: Lessening the Impact of Adverse Selection through Buyer Trust

This research extends overlapping streams of research examining asymmetric information, adverse selection, and buyer trust by presenting an empirical investigation of the process by which a market for “lemons” emerges in the claiming market for thoroughbred racehorses. The study focuses attention on the potential of quality signals and buyer trust to lessen the impact of adverse selection. Incorporating concepts from economics, marketing, and psychology, a conceptual model suggests that adversely selected racehorses, distinguished by an unintentional signal from sellers to potential buyers, will be priced lower than otherwise similar racehorses perceived to be less subject to adverse selection. Data from one day of claiming races at 16 American racetracks (744 racehorses) are used to test this study hypothesis. Results provide evidence for adverse selection and a mitigating quality signal in the thoroughbred claiming market. Implications for buyers and sellers in this market, as well as more general implications, are discussed and an avenue for future research is proposed.     

Monopolistic competition: CES redux?

We study the competitive and reallocation effects of trade opening in monopolistic competition. To this purpose, we generalize the Melitz (2003) setup with heterogeneous firms and fixed and variable trade costs beyond the CES to the case of additively separable utility functions. We find that extensive margin (Melitz-type selection) effects are robust to relaxing the CES assumption. Intensive margin effects (market share reallocations across inframarginal firms) and competitive (markup) effects are instead fragile. An important implication is that measured productivity gains from trade opening are no longer ensured with non-CES preferences. We discuss our results in the light of alternative setups featuring non-additive preferences, strategic interaction and consumers' preference for an ideal variety.     

Cost of Capital Under Local Constraint on Debt Financing:

A unique constraint on financing of direct foreign investment by MNCs IS a total or partial prohibition on debt financ- ing in many Islamic countries. This paper analyzes the implications of such a conslraint for an MNC's financing and investment deci- sions. The comparative investment levels under alternative financing instruments based on profit and loss sharing (PLS) contracts are examined considering the effects of market imperfections and secu- rity related differences with reference to the existing literature on capital structure. The analysis shows that when debt financing is constrained the cost of capital to a firm will be higher and the invest- ment levels lower.     

Adverse selection costs: A study on the Chinese stock market

Employing a bid-ask spread model applicable for order-driven market, this paper decomposes the bid-ask spread of Shanghai Stock Exchange (SSE) into adverse selection and order processing cost components to investigate the relationship between the components of bid-ask spread and order size. It examines the impacts of firm size, price, trading activeness, and volatility on adverse selection cost, and explores the intraday pattern of adverse selection costs and informative trading. Results show that adverse selection costs increase with trade scale. However, order processing costs do not exhibit the economies of scale. Stocks of large firms, which are high-priced and actively traded, have relatively low adverse selection costs; stocks with large volatility have relatively high adverse selection costs. Moreover, this paper finds that the adverse selection component of bid-ask spread in the Chinese stock market exhibits an L-shaped intraday pattern, which implies that heavy trading around market opening is dominated by informative trading, while heavy trading near market closing is dominated by liquidity trading.     

RISK METRICS AND FINE TUNING OF HIGH‐FREQUENCY TRADING STRATEGIES

We propose risk metrics to assess the performance of high‐frequency (HF) trading strategies that seek to maximize profits from making the realized spread where the holding period is extremely short (fractions of a second, seconds, or at most minutes). The HF trader maximizes expected terminal wealth and is constrained by both capital and the amount of inventory that she can hold at any time. The risk metrics enable the HF trader to fine tune her strategies by trading off different metrics of inventory risk, which also proxy for capital risk, against expected profits. The dynamics of the midprice of the asset are driven by information flows which are impounded in the midprice by market participants who update their quotes in the limit order book. Furthermore, the midprice also exhibits stochastic jumps as a consequence of the arrival of market orders that have an impact on prices which can give rise to market momentum (expected prices to trend up or down). The HF trader's optimal strategy incorporates a buffer to cover adverse selection costs and manages inventories to maximize the expected gains from market momentum.     

Volatility spillover and hedging effectiveness among China and emerging Asian Islamic equity indexes

We study the volatility spillover between China and Asian Islamic stock markets. We use a sample of six Islamic MSCI indices from the Asian region, namely China, India, Malaysia, Indonesia, Korea and Thailand obtained from MSCI (Morgan Stanley Capital International). In this paper we analyze the importance of considering spillover effects between emerging Asian Islamic indexes based on the Bivariate VARMA-BEKK-AGARCH model of McAleer et al. (2009), which includes spillover and asymmetric effects. We compute after the effectiveness of portfolio diversification based on the conditional volatility of returns series. Results show a significant positive and negative return spillover from China to selected Asian Islamic stock market and bidirectional volatility spillovers between China, Korea and Thailand Islamic market showing evidence of short-term predictability on Islamic Chinese stock market movements. However there is no short term volatility persistence in India, Indonesia and Malaysia. GARCH results show no persistence in volatility spillover effect in long term from Chinese to Indian, Indonesian and Korean Islamic stock market. Our findings are beneficial for international portfolio diversification for policy makers and investors since the results of portfolio management and hedging effectiveness ratio are different to previous studies.     

An Investigation of the Degree of Market Power in the Greek Manufacturing and Service Industries

This paper investigates the degree of market power in the Greek manufacturing and service industries over the period 1970–2007. The markup model developed by Hall (1988) and Roeger (1995) is taken into consideration where market power is expressed as the difference between the selling price and the marginal cost of production. The analysis will be conducted in three steps; the first step estimates the price-cost margin of the manufacturing and services industries over 1970–2007; the second step applies the cross section specification under which the markup ratio is obtained for the 23 manufacturing and 26 service 2-digit ISIC sectors of the panel sample; and the third step estimates the price-cost margin of the manufacturing and services industries for each year over 1973–2007 by employing the Hall-Roeger time series specification. The empirical findings suggest that both industries exert a positive markup ratio; however, the service industry appears to be less competitive than the manufacturing industry.     

The investigation on dimensions of e-satisfaction for online shoes retailing

Purpose—Online retailing has become a standard component in companies' multi-channel structure. This trend also involves an increasing number of experience attribute dominated products, which traditionally rely on brick-and-mortar retailers. These manufacturers have started to open their own online retail stores. This study identifies the key determinants of e-satisfaction at different stages of shoes online shopping process.Design/methodology/approach—We collect consumers' reviews about their online shopping experiences from online review websites. We use both qualitative and quantitative approaches to analyze the dataset, and investigate the complete process of consumers' e-tailing experiences.Findings—this research identifies the two key factors driving e-satisfaction of purchasing experience attribute dominated products online: product selection and customer service. In particular, our findings show that product selection is critical for e-satisfaction in the pre-purchase stage, and that customer service is more important in the post-purchase stage. Lastly, the study finds that manufacturers' websites often receive more negative reviews because of their poor service recovery strategies in the post-purchase period.Research limitations/implications—This study emphasizes the importance of adopting a dynamic approach by considering various stages of the consumer's online shopping experience. This study focuses on one specific experience good; the shoe industry.Practical implications—The results of this study are invaluable to firms interested in providing experience attribute dominated products online. Our findings indicate that product selection and especially post-purchase service are critical for a successful e-tailing.Originality/value—This paper emphasizes the importance of taking a dynamic view to investigate consumer's e-tailing experience. We adopt both qualitative and quantitative approaches in our study.     

Which firms do prefer Islamic debt? An analysis and evidence from global sukuk and bonds issuing firms

The Islamic debt instrument sukuk has been in the market for two decades; still, we do not know why a firm prefers an Islamic debt over conventional debt, set aside religiosity issue. We argue there is a genuine reason to choose Islamic debt because it has lighter indebtedness, benefits of avoiding external monitoring, and tax incentives. Based on the cross-country data for 346 firms issuing dollar-denominated global sukuk and bonds, we find that firms that prefer Islamic debt and issue sukuk are financially more unstable, and thus exposing to higher insolvency risk as compared to bond issuing firms.
