Oliveira","doi":"10.2139/ssrn.3525004","DOIUrl":"https://doi.org/10.2139/ssrn.3525004","url":null,"abstract":"Freight trip generation models essentially use the least-squares estimation technique, losing in part the power of weighted least squares, least squares techniques in two stages, and instrumental variables that could address the complexities of the transport phenomenon that has repercussions in the explanatory and dependent variables, as well as in the hypotheses related to the behaviour of the estimation error. In this sense, this paper presents an alternative modelling to estimate freight trip generation using different techniques dealing with the problems arising from linear regression and obtaining efficiency in the estimation models. Also, an exercise considering warehouse freight trip generation modelling is presented using the traditional technique of least squares and comparing the results with least-squares weighted, least-squares techniques in two stages and instrumental variables. The results indicate that the proposed modelling improve linear models to predict freight trip generation estimation, guaranteeing better adherence than traditional modelling.","PeriodicalId":324932,"journal":{"name":"TransportRN: Freight Distribution Clusters (Logistics Zones) (Topic)","volume":"99 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127055862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"The Grouping Policy in Japan’s Coastal Shipping Market","authors":"Satoru Hashimoto","doi":"10.2139/ssrn.3432172","DOIUrl":"https://doi.org/10.2139/ssrn.3432172","url":null,"abstract":"This study aims to analyze the market structure of the coastal shipping industry in Japan. Based on 153 observations using balanced panel data for the period 2000–2016, we estimate the market-wide cost function and total factor productivity (TFP) growth rate, and then provide some policy implications from the results. We also estimate the long-term total cost function and analyze the economies of scale and the TFP growth rate. The results indicate that the grouping policy is conducive to achieving economies of scale. Hence, we conclude that it is worth continuing the grouping policy for the benefits it provides in terms of management efficiency.","PeriodicalId":324932,"journal":{"name":"TransportRN: Freight Distribution Clusters (Logistics Zones) (Topic)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114265604","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"International Business Asymmetries in an Enlarging Environment - Practice and Operating Developments in the EU","authors":"Mario Pines","doi":"10.2139/SSRN.2239690","DOIUrl":"https://doi.org/10.2139/SSRN.2239690","url":null,"abstract":"The perspective of a successful continental economic integration relies on specific stratified beneficial factors or combination of factors as well as on the evolution of institutional and legal business homogeneous local infrastructures. Investments and international outsourcing activities are generally stimulating the globalization processes, the consequent wave of mergers and acquisitions, especially in the finance, commerce and telecommunication sectors, are consolidating the efficient enterprises structure and their international headquartering and development. A heated debate is going on among academics and politicians and bills seeking to restrict outsourcing forwarding industrial activities have been recently discussed in several European States; it is difficult to deal with these issue dispassionately, considering the European enlargement process and no attention has been put on pre-existing and growing spectacular asymmetries in both finance logistics and transportation industry. Outsourcing and FDI and global logistics are probably a plus for the economy in the long run. Any economic change, whether arising from trade or technology, can cause painful dislocations for some activities, anyway large scale emigrations would represent a worse scenario.During the last century, the historical lag between the institutional political regulations and current business requirements and perspectives have been advocating some asymmetries in a highly diverging environment and the viable solutions adopted reflect ancient advantages and leave unexploited some local favorable provisions and natural assets. In restructuring and discovering the business and firm appropriate configuration, within the competitive frameworks, the successfully growing enterprise eventually requires a global strategic integration as an option to redevelop an international locally self-sustaining production independent units network. Pending the EU association and adhesion phases, the relocating factors are showing an integrating economy over all the European Continent with some few specific coordinating, managing and financial pooling centers. All these factors should be considered from the legislative and institutional bodies stemming from a national oriented economic pattern. The global economy as a resulting alternative to outdated autarchic attitudes in a competitive global market must reconsider some preexisting asymmetries within the European scenario.","PeriodicalId":324932,"journal":{"name":"TransportRN: Freight Distribution Clusters (Logistics Zones) (Topic)","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133126973","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
