An Internet presence is a critical early component in the process of building towards a fully operational and unified e‐commerce strategy. E‐commerce has significantly impacted logistics/supply chain strategies and the development and implementation of a website have become key issues for many firms within the transportation industry. This study provides an overview of website content within the motor carrier industry. Content analysis was used to assess the site design, informational content, and the interactive content of 152 motor carrier websites, and to compare the features offered on the Top 100 motor carrier firm websites with those offered on the sites of smaller carrier firms.  相似文献

We consider a differential game of R&D competition and explore the impact of rivalry on the firms' investment behavior over time. Using closed-loop strategies and hence allowing for strategic interactions among rival firms we show that R&D spending by the individual competitor is increased due to competition in the race for priority. This leads us to argue that competitive encounters enhance R&D activities at the same time as increasing efficiency in the race for a technological breakthrough.  相似文献

This paper analyzes the costs of job loss over the years of a booming economy, 2003–2008, using unique data from the Russian Longitudinal Monitoring Survey. In addition to analyzing standard labor market outcomes, such as forgone earnings, employment, hours worked and wage penalties, our unique data set allows us to investigate additional non-wage costs of displacement, in particular, fringe benefits, the propensity to have an informal employment relationship or a temporary contract. We find that displaced individuals face large foregone earnings following displacement, which are heterogeneous across education and ownership type of firm from which the worker separated. There is no evidence of wage penalties for re-employed displaced workers. However, we find an increased probability of working in informal or temporary jobs if previously displaced and a reduction in the number of benefits.  相似文献

Although software licenses usually range among the most expensive items within the IT budget, they still lack the necessary attention by many companies. Therefore, most companies inadequately have implemented their software asset management neglecting further potential for cost reduction, which can be obtained by optimizing the use of different license types. This paper shows how possible savings can be realized by combining different types of licenses in a license portfolio. The model presented is based on the most common license types considering different user groups as well as their behavior. Additionally to cost risks, the risk of service quality is also taken into consideration. The following examples illustrate the model’s high relevance and show how it can be applied in practice.

Are low wages a way for the unemployed to switch to higher-paying jobs? Using data from the British Household Panel Survey, the labour market dynamics of unemployed, low-paid and higher-paid employed men are analysed. Moreover, the respective (un)employment duration and occupational skill level are accounted for. Results show that in general low wages significantly reduce the risk of future unemployment and increase the chances of ascending the salary ladder, especially in the case of long-term unemployment (>360 days). Furthermore, the occupational skill level has a substantial influence on the upward mobility of low-paid jobs: individuals working in the initial period in a low-paid and higher-skilled occupation have on average an 11 percentage points higher probability of entering higher pay compared to when working in a low-paid and low-skilled occupation.  相似文献

Productivity slowdown plays a prominent role in the build-up of the euro area crisis. This phenomenon affected member countries asymmetrically, causing divergence in their productivity trends. Recent research traces this divergence back to monetary integration. After reviewing the arguments that link real “disintegration” of the euro area to its monetary integration, we assess them empirically by modelling the evolution of labour productivity using a panel of sectorial data. The results indicate that monetary unification may actually have fostered divergence in productivity trends, and suggest some economic policy measures that could prevent further divergence.  相似文献

Using daily abnormal currency returns for the universe of countries with flexible exchange rates, we show local currency depreciations ahead of unscheduled, public sovereign debt downgrade announcements. Consistent with the private information hypothesis, the effect is stronger in lower institutional quality countries and holds after we control for concurrent public information and for publicly available rumors about the forthcoming downgrades. Our results persist when abnormal currency returns are adjusted for global carry and dollar risk factors, world equity and bond returns, as well as local stock market returns. Finally, the currency depreciations are permanent, providing evidence for a link between fundamentals and currency markets.  相似文献

This paper re‐formulates and tests statistically a hypothetical law (HL) of capital accumulation that manifests itself in three scenarios for Italian economy. HL refines Verdoorn law and ‘Ricardian’ relationship between employment and returns; it generalizes neoclassical and Goodwinian models. Big cycles are not sustainable in inertia Scenario I. Lowering direct diseconomy of scale does not alter a non‐trivial stationary state in stabilization Scenario II. Weakening an inverse relation between employment ratio and growth rate of capital intensity raises stationary relative labour compensation without deteriorating profitability in stabilization Scenario III. Stationary states with zero relative labour compensation are not economically relevant.  相似文献
