Stock exchange mergers and market efficiency

The aim of this article is to examine the impact of stock exchange mergers on the degree of informational efficiency. For this purpose, we apply the generalized spectral shape test for the martingale difference hypothesis to the stock returns before and after the 31 domestic and cross-border mergers completed from 1997 to 2011. The test is conducted with moving subsample windows, allowing us to detect the periods of (in)efficiency, and thus to conduct a comparative analysis for pre-merger and post-merger periods. We find that higher levels of efficiency are less frequent than lower levels of efficiency after a stock exchange merger. We also find that the impact on the level of efficiency depends on a range of merger characteristics such as the level of development, size, geographical diversification and industrial diversification of stock exchange.     

How resilient is La Réunion in terms of international tourism attractiveness: an assessment from unit root tests with structural breaks from 1981-2015

Even if local policymakers increasingly claim that tourism is one of the key factors of future economic development for the French small island La Réunion, international tourist arrivals are observed to be locked in a stagnation phase since the beginning of the 2000s. Starting from this stylized fact, this article aims to study if this phenomenon results from major external events hurting this economy regularly. Next, by using univariate unit root procedures with structural breaks, we test for evidence of permanent or transitory effects of external shocks on international tourist inflows (total, by source markets, and by category) over the period 1981–2015. Finally, the empirical analysis allows us to reject the null of a unit root. Then, stagnation of tourism arrivals to La Réunion is not due to exogenous shocks but probably results from endogenous impediments within the domestic tourism industry and unsuitable public policies.     

Testing the martingale difference hypothesis in CO2 emission allowances

This study examines the martingale difference hypothesis (MDH) for the carbon emission allowance market within the European Union Emission Trading Scheme (EU ETS) during the Phase I and the Phase II, using both daily and weekly data over the 2005–2009 period. We analyze the MDH for spot prices negotiated on BlueNext, European Energy Exchange and Nord Pool along with futures prices negotiated on BlueNext and European Climate Exchange, using the new variance ratio tests developed by Kim (2009) and the generalized spectral test proposed by Escanciano and Velasco (2006). For the Phase I, the results show that the spot price changes of these three markets are predictable, suggesting the possibility of abnormal returns through speculation, except during the period April 2006 to October 2006, namely after the compliance break and before the ECs of stricter NAP II. Finally, we find that the CO₂ spot and futures price changes are unpredictable during the Phase II because we failed to reject the MDH based on both daily and weekly data. Thus, these markets are found to be weak-form efficient.     

Evidence of the impacts of public e-procurement: The Portuguese experience

This paper analyses public e-procurement implementation and emphasizes its main difficulties and impacts in relation to the type of public organizations. The primary impacts and changes in the Portuguese public sector are analyzed within the new legal framework, which adopts mandatory e-procurement for any open, restricted or negotiated procedure. In this sense, two surveys carried out in consecutive years were conducted to assess the implementation difficulties and impact of e-procurement in the Portuguese public sector.The major value of this research is that it presents and discusses, for the first time, evidences about difficulties and impacts on the mandatory adoption of public e-procurement, based on the case of Portugal. The results show that the entities’ administrative level influences the e-procurement implementation, which is influenced by the innovation adoption process.     

Co-presence and mobile apps: Technology's impact on being with others

Despite a lack of theoretical understanding regarding how consumers react when using mobile applications in a store, the latter are being used more and more often in shared consumption areas. This research explores the impact that using a mobile application has on perceptions of co-presence. Depending on the consumption experience stage, this technological tool can be a social facilitator that enhances interactions with companions or a device that makes it possible to reduce a negative crowd impression. This paper is positioned at the intersection of interpersonal influence research and research focused on mobile technologies' effect on the purchasing process. It may interest managers of sites where there is high co-presence and where a mobile application might reduce negative crowd impressions and facilitate in-group sharing.     

Firm Turnover and Productivity Growth in Canadian Manufacturing and Services Industries, 2000 to 2007

This paper examines the differences and similarities in the nature of the competitive process for a cross section of Canadian industries. It studies the intensity and the effectiveness of entry, the relationship between turnover within incumbents and the intensity of entry, and the failure process underlying the exit of entrants. Finally, it asks how differences in these processes relate to the contribution that turnover makes to productivity growth. Differences across industries both in the effectiveness of the entry process and the contribution of turnover to productivity growth are related to the conditions that permit entry at relatively large scale and regulatory conditions in the industry. Industries where entrants are capable of establishing a relatively large footprint are generally those where entrants capture more of the market, where there is more intense turnover among incumbents and where a larger proportion of productivity growth comes from turnover due to both entry and exit and changes in the market position of incumbents. Industries where regulation attenuates freedom of entry have a different though related profile. Even here, turnover contributes to productivity growth.     

How financial intermediation impacts on financial stability?

The great financial crisis widened the role of financial intermediation in financial stability. This study develops a new financial intermediation variable, credit cash flow (CCF), which enables measurement of the net financial flow resulting from loan activity. An analysis provides evidence that CCF affects the capital buffer via credit gap behaviour, thus indicating the existence of a channel between the CCF and the capital buffer. Such a link offers the policy-maker the possibility to monitor the behaviour of financial intermediation carried out by banks, in order to avoid the outbreak of financial instability events.     

Financialization,Globalization and the Management of Skilled Employees: Towards a Market‐Based HRM Model in Large Corporations in France

The article analyses the transformation of HRM policies for skilled employees in large corporations in France over the last decade in relation to changes occurring in governance patterns and competitive strategies. First, we highlight a shift towards globalization and financialization in the strategic management of large corporations in France, entailed by the diffusion of a shareholder form of capitalism in that country. Second, we characterize the market‐based HRM model applied to skilled employees under these new strategic orientations and the diversity of ways in which these transformations are perceived depending on employees' age and level of responsibility within the firm.     

Large shocks in U.S. macroeconomic time series: 1860�C1988

In this paper, we examine the large shocks due to major economic or financial events that affected U.S. macroeconomic time series on the period 1860–1988, using outlier methodology. We show that most of these shocks have a temporary effect, showing that the U.S. macroeconomic time series experienced only few large permanent shifts in the long term. Most of these large shocks can be explained by major recessions and World War II as well as by monetary policy for the interest rate data. We also find that some economic events seem to have the same effect (immediate, transitory or permanent) on a number of macroeconomic series. Finally, we show that most macroeconomic time series do not seem inconsistent with a stochastic trend once we adjusted the data for these shocks.
