This paper investigates internal and external barriers influencing the different dimensions of firm service innovativeness and the moderating effect of transformational leadership on these relationships in an emerging economy, namely, Turkey.

The hypotheses were tested using cross-sectional survey data from 148 hotels. The authors use regressions to analyze the data set.

The results demonstrate that barriers to innovation need not necessarily impede firm service innovativeness at all times; some of these so-called “barriers” may even act as catalysts that improve firm’s likelihood of adopting innovations. More importantly, the findings suggest that a transformational leadership style alleviates the negative influence of internal barriers on internal service innovativeness dimensions of process, strategic and behavioral innovativeness.

The positive effect of transformational leadership lessening the detrimental impact of barriers to innovation is a topic in need of research. In addition to examining this phenomenon in a developing country, the authors choose a service retailing industry as a study context: hospitality/tourism. The main reason for choosing this industry is that there is little empirical evidence of service innovation activity in this industry despite the fact that it contributes to a large extent to employment and gross domestic product in most emerging economies, and it is, in fact, a fairly innovative industry. Furthermore, this study presents a unique perspective by investigating small- and medium-sized enterprises (SMEs).

March’s 1991 work on exploitation and exploration has been studied in many different industries. The purpose of this paper is to analyze signals emanating from exploration and exploitation alliances within the pharmaceutical industry context. Specifically, the authors explore market reactions to announcements of alliance formations based not only on alliance type but also in terms of their marketing intensity and leverage.

The authors employ a two-stage event-study market model using a two-day event window (event days 0, +1), creating cumulative abnormal returns (CARs). In the second stage, the authors regress the CARs against an array of control and explanatory variables.

Findings suggest that even though firm announcements of exploration and exploitation formations initially generate favorable market reactions, the former has a greater impact on CAR relative to the latter. Furthermore, leverage and marketing intensity moderate the relationship between firms’ alliance formation announcements and CARs generated. In particular, firms’ alliance formation announcements generate relatively greater market reactions at lower (higher) levels of the firm’s leverage (market intensity).

Event studies are valuable for gauging initial impressions of management action, but they are not meant to address long-term value creation. While market reactions suggest the likelihood of an alliance’s success or failure, managers also assess the risk to a firm’s financial health should the alliance fail. As a result, announcements that signal the firm has discretionary capabilities to ameliorate the effect of a failed alliance are better received.

This study is the first to analyze the stock market’s perception and valuation of different types of risk, classified by exploration vs exploitation alliances. The study also contributes to the literature by analyzing how investors use the information about a firm’s financial leverage and marketing activities to fine-tune their valuation of different types of risk-taking activities.

The purpose of this paper is to test the weak form of the efficient market hypothesis (EMH) using monthly data from 2004M08 to 2018M04 for two Canadian stock indices: the Islamic (DJICPI) and the conventional (CCSI). This paper investigates whether Islamic and/or conventional stock market would be efficient through the non-stationarity test of the stock indices.

The authors conduct the linearity test of Harvey et al. (2008) to identify whether the considered series has linear or nonlinear behavior. If the time series exhibits nonlinear evolution, then the authors apply nonlinear unit root tests (three KSS type tests and Sollis tests).

Linearity test results say that LCCSI has nonlinear behavior, while Dow Jones Islamic Canadian Price Index, LDJICPI, is a linear process. Then, the findings of this paper show that only Canadian Islamic Price Index (DJICPI) has the characteristics of random walk indicating that only conventional stock markets are inefficient. The major implication is that in Canada, fund managers and investors can (cannot) enjoy excess returns to their investment in conventional (Islamic) stock market.

Numerous empirical studies of the weak EMH are carried out within a linear framework. However, stock indices can show nonlinear behavior as a result of 2008 global financial crisis. To contribute to the existing literature on the Islamic and conventional stock market efficiency, the authors take into account both structural breaks and nonlinearity. Thus, as a testing strategy for weak EMH, the authors perform (Harvey et al., 2008) linearity test to examine the presence of nonlinear behavior and correct for outliers effect when it is needed.
