This paper uses regional input-output tables to analyse the long-term impact resulting from the implementation of the newly irrigated areas provided for under the terms of the Ebro Basin Hydrological Plan. We have described the whole process by way of two consecutive stages. In the first, where the final demand is fixed, we use a demand-driven input-output model and we incorporate technical change through the reduction of the coefficients. In the second, the output of all sectors increases, with the increases in the vector of output being proportional to the forward linkages vector of the Agriculture sector. In this stage, our objective is to obtain a final demand vector that ensures that the agricultural value added increases to a prescribed value of v 1 *. Whilst the results demonstrate the positive effects of the transformation, they also reveal effects of a very different character in each sector. Thus, the Agriculture, Livestock and Agri-food industry sectors show significant increases in their gross outputs caused by the forward effects, whilst the Energy, Metal and Chemicals sectors reduce their outputs. These results shed light on the contradictory nature of the processes of development and technical change.  相似文献

Target firms in Australian takeovers are required to commission the preparation of an independent expert report in circumstances where there is a perceived conflict of interest with the bidder. As approximately half of these reports are prepared by firms with which the target has other business dealings, concern has been expressed over the quality of these reports due to the suggestion that such reports are provided at lower fees. We examine the 191 independent expert reports provided in all 649 Australian takeover bids initiated in the period 1990 to 2000 inclusive. Using an expert-fee model, we find that the fees for reports by experts with other business dealings with the target are not lower than those of unrelated experts. In addition, the results indicate that experts with other dealings with the target provide reports with a significantly smaller valuation range, consistent with these reports being of higher, rather than lower, quality. Our findings are inconsistent with the U.S. and New Zealand experience of prohibiting audit firms from providing valuation advice in takeovers.  相似文献

Abstract:  This paper presents a model linking two financial markets (stocks and bonds) with real business cycle, in the framework of the Consumption Capital Asset Pricing Model with Generalized Isoelastic Preferences. Besides interest rate term spread, the model includes a new variable to forecast economic activity: stock market term spread. This is the slope of expected stock market returns. The empirical evidence documented in this paper suggests systematic relationships between business cycle's state and the shapes of two yield curves (interest rates and expected stock returns). Results are robust to changes in measures of economic growth, stock prices, interest rates and expectations generating mechanisms.  相似文献

The main aim of this paper is to evaluate the disparities in the Italian regions on the demand side. In more detail, an attempt will be made to find if the consumption behaviour of Italian households is different in the regions. With this in mind, Istat's 2000 Italian Family Budget data set was analysed. The data in question, which were collected through a two‐stage sample over Italy's 20 regions, contains information regarding the expenses of approximately 23,000 households. In this analysis, both households and regions are considered as units: households are nested in the regions so that the basic data structure is hierarchical. In order to take this hierarchical structure into account, a multilevel model was used, making it possible for parameters to vary randomly from region to region. The model in question also made it possible to consider heterogeneity across different groups (regions), such as stochastic variation. First, regional inequalities were tested using a simple model in which households constituted the first level of analysis and were grouped according to their region (the second level). As a second step, and in order to investigate the interaction between geographical context and income distribution, another model was used. This was cross‐classified by income and regions. The most relevant results showed that there is wide fragmentation of consumption behaviour and, at the same time, various differentiated types of behaviour in the regions under analysis. These territorial differentials become clear from income class and items of consumption.  相似文献

The aim of this paper is to analyse the responsibility of Spanish demand composition (particularly private and public consumption) in the actual levels of atmospheric pollution in Spain. To that end, and on the basis of an input–output model, we set out to identify the environmental pollution generated both directly and indirectly by the economic sectors in order to obtain a determined final demand. We focus on three atmospheric pollutants, namely SOx, NOx and CO2. After identifying the key sectors in the generation of these types of pollution, we estimate the effect that a change in final consumption will have on the global level of pollution. As a consequence, we can evaluate the effectiveness of different demand policies when seeking to control this global pollution. These policies, directed mainly towards a change in private and public consumption, can hopefully contribute towards the objective of achieving sustainable development.  相似文献

The aim of the European Commission's Single European Sky initiative is to promote a series of structural changes within Air Transport to help improve its efficiency, continuity and sustainability. One of the key elements of the air transport system is Air Traffic Services (ATSs), which must guarantee safe and fluid operations. The Single European Sky initiative puts in place a series of mechanisms to replace the existing public monopolies with free market models. Taking advantage of this new framework, Spain has initiated a process of liberalisation of ATS Services, which may provide a business opportunity for operators with an interest in the area of air transport, and European providers who wish to expand their markets. This document sets out the new legal framework that has been put in place in Spain to promote this process, indicating the motives of these actions and the main implications the process will have, whilst maintaining the objective of guaranteeing continuity of service, and avoiding any barriers to entry, which changes of this type can give rise to.  相似文献

ABSTRACT

Economic growth has different impacts on gender gaps. In recent decades the growing participation of women in the labour market has reduced the gender employment gap, however a notable gender pay gap still persists standing at around 15% on average in the European Union. In this context, this paper evaluates the impact of economic growth patterns on the evolution of gender employment and pay gaps. First, sectorial feminization, direct discrimination, and structural change factors are identified and evaluated as ways to explain changes observed in the gender pay gap. Second, we explore the influence of demand, technology, and intensity factors on the evolution of employment combining gender, skill, sectorial, and temporal perspectives. As a case study, we examine Spanish economic growth from 1980 to 2007 and the influences on the size, composition (by skill), and distribution (by sector) of female and male employment, as well as the consequences for gender gaps. Our results show that structural change contributed to reduce the gender employment gap in Spain; while the evolution of the gender pay gap is less conclusive, following a sort of inverted U-shape. This paper shows the suitability and potential of the multisectorial input–output framework to analyse structural and technological changes and their impacts on the gender employment and pay gaps.  相似文献

In public procurement auctions, governments routinely offer preferences to qualified firms in the form of bid discounts. Previous studies on bid discounting do not account for affiliation – a form of cost dependence between bidders that is likely to occur in a public procurement environment. Utilizing data from the New Mexico Department of Transportation’s Resident Preference Program, I develop and estimate an empirical model of firm bidding and entry that allows for affiliation in firms’ project costs. I find evidence of affiliation and show how it changes preference auction outcomes.  相似文献

Our paper investigates the integration of anticorruption practices, corporate strategy and business processes of contemporary organisations to provide a new and emerging sustainable governance model. Using the single case study approach to answer our research question, we provide novel evidence from the analysis of the Italian manufacturing company Acciai Speciali Terni Spa. Our case study interprets a consolidated entrepreneurial experience, constructing an integrated meta‐management framework of anticorruption practices. Enriching existing literature, we have adopted the frameworks by Asif et al., (2010) and Asif et al., (2011) to test results and obtain general perspectives and practical implications for organisations, regulators and governments, proposing a sustainable governance model to prevent corruption and bribery.  相似文献

Private efforts to prevent and control biological pests and infectious diseases can be a public good, and so incentivising private biosecurity management actions is both desirable and problematic. Compensation contracts can encourage biosecurity efforts, provide support against the collapse of economic sectors, and create an insurance network. We conceptualise a novel biosecurity instrument relying on formal compensation private–public partnerships using contract theory. Our framework explains how the public sector can harness increased private biosecurity measures by making payments to agents which depend both on their performance and that of the other stakeholders. Doing so allows the government to spread the risk across signatory agents. The framework also improves our understanding of government involvement due to public effects of biosecurity, influenced by the private agents’ capacity to derive private benefit from their own efforts on monitoring and control. Lastly, these theoretical results provide a foundation for further study of contractual responsibility sharing for pest management.  相似文献
