In this paper, forecasting models for the monthly outgoing telephone calls in a University Campus are presented. The data have been separated in the categories of international and national calls as well as calls to mobile phones. The total number of calls has also been analyzed. Three different methods, namely the Seasonal Decomposition, Exponential Smoothing Method and SARIMA Method, have been used. Forecasts with 95% confidence intervals were calculated for each method and compared with the actual data. The outcome of this work can be used to predict future demands for the telecommunications network of the University. 相似文献

Abstract We conduct an update of the ranking of economic journals by Kalaitzidakis, Mamuneas, and Stengos (2003) . However, our present study differs methodologically from that earlier study in an important dimension. We use a rolling window of years between 2003 and 2008, for each year counting the number of citations of articles published in the previous 10 years. This allows us to obtain a smoother longer view of the evolution of rankings in the period under consideration and avoid the inherent randomness that may exist at any particular year, because of new entrants. 相似文献

Recent methodological developments provide a way to incorporate the temporal dimension when accounting for spatial effects in hedonic pricing. Weight matrices should decompose the spatial effects into two distinct components: bidirectional contemporaneous spatial connections; and unidirectional spatio-temporal effects from past transactions. Our iterative estimation approach explicitly analyses the role of time in price determination. The results show that both spatio-temporal components should be included in model specification; past transaction information stops contributing to price determination after eight months; and limited temporal friction is exhibited within this period. These findings highlight the decidedly non-linear temporal patterns of such information effects. 相似文献

This paper derives analytical solutions for arbitrage-free bond yields when the short-term interest rate follows an autoregressive process with the intercept switching endogenously. This process from the SETAR family is especially suited to capture the near-unit-root behaviour typically observed in the evolution of short-term interest rates. The derived yield functions, mapping the one-month rate into n-period yields, exhibit a convex/concave shape to the left and right of the threshold value, respectively, a pattern which is also found in US bond yield data. The longer the time to maturity, the more distinct the nonlinearity of the yield function becomes. 相似文献

Current literature has largely ignored the fact that some organizations are highly selective when admitting new agents while
others are more open. In addition, some organizations audit or sort agent behavior within the organization more aggressively
than others. One might expect a priori that closed, highly selective, organizations would always be more efficient because
they screen out the worst types, which could lead to better agent behavior. We show that this is not the case. Specifically,
when agent behavior in equilibrium is uniform across organizations (i.e., when the number of agents behaving the same way
is identical), closed organizations are inefficient. However, when agent behavior varies across organizations, closed organizations
may or may not be inefficient, depending on net payoffs to the organization and the agents. Our analysis implies that organizations
should choose the open type when screening or sorting costs are high, when there is a high frequency of good agent types in
the population, when agent misbehavior does not reduce output significantly, and when penalties for misbehavior are large.

Summary. We examine the strategic role of information transmission in a repeated principal-agent relationship where the agent produces
information that is useful to the principal. The agent values continuous employment for the principal because he makes a relationship-specific
investment that can yield rents to him when the relationship is renewed. Assuming that the parties are sufficiently impatient,
we show that full disclosure of the information produced occurs early in the relationship when the principal can commit to
a long-term relationship, when the agent observes his valuation of continuous employment after making a report on information
produced, or when the agent obtains a low valuation of continuous employment before making a report. By contrast, a strategic
delay in the transmission of information occurs when the principal can only commit to a short-term relationship and the agent
obtains a high valuation of continuous employment before making a report.

This paper investigates the link between governance and foreign direct investment in the case of 14 transition countries by using a panel gravity model approach in two alternative ways. First, the level of governance in the target country is studied. Second, the absolute difference in the governance level between the source and target country is investigated. In both cases the results suggest that the lack of good governance does not deter, in fact it encourages, foreign direct investment. 相似文献

Strategic tools are indispensible for business and competitive analysis. Yet we know very little about managers' internal logic as they put these tools into practical use. We situate our study in a business school context using action learning prior to the manifestation of practice to complement our understanding of practice. Using Personal Construct Theory and Repertory Grids, our mid‐range theorizing showed that, contrary to current thinking about strategic tools, managers think in dualities (often paradoxically) and have a preference for multiple‐tools‐in‐use, tools that provide different perspectives, peripheral vision, connected thinking, simultaneously help differentiate and integrate complex issues, and guide the thinking process. These findings are important for designing better tools and the nurturing of critical managerial competencies needed for a complicated world. Our study's focus also has wider implications for scholars as we see our own material evaluated by those who will put these lessons into practice. 相似文献

We compare the sensitivity analysis of cross-country growth regressions based on extreme bounds analysis to a more direct
specification testing approach using non-nested hypotheses tests. The results suggest that those specifications that are adequate
are also those that include two of the only few conditioning variables that are found to be robust, namely the standard deviation
of inflation and the standard deviation of domestic credit.
