Sources of gains from international portfolio diversification

This paper looks at the determinants of country and industry specific factors in international portfolio returns using a sample of forty eight countries and thirty nine industries over the last three decades. Country factors have remained relatively stable over the sample period while industry factors have significantly increased during the last decade and dropped again since 2000. The importance of industry and country factors is correlated with measures of economic and financial international integration and development. We find that financial market globalization is the main driving force behind the changes in relative magnitude of the different shocks. Country factors are smaller for countries integrated in world financial markets and have declined as the degree of financial integration and the number of countries pursuing financial liberalization has increased. Higher international financial integration within an industry increases the importance of industry factors in explaining returns. Economic integration of production also helps in explaining returns. Countries with a more specialized production activity have higher country shocks.     

Workload control under continuous order release

Workload control is a production planning and control concept specifically designed for complex manufacturing environments. Past research on Workload control has been essentially focused on discrete order release. This means that release of orders to the shop floor takes places on a periodic basis. Continuous order release has been somehow neglected, in spite of its apparent potential for improving system performance, including the reduction of order flow times. This paper presents a simulation study of this order release approach. The study contributes for improving the basis for setting workload norms, selecting the workload control strategy and deciding upon routing alternatives under continuous order release.     

Innovation Economy,Productive Public Expenditure and Economic Growth

Multidisciplinary innovation is the main engine of growth for an increasing number of economies. Innovation requires the participation of and interaction between all economic agents. It also requires public spending on education, research and infrastructures. Our main goal is to emphasize the government's role in a growing innovation economy. Developing a non‐scale, idea‐based, one‐sector growth model with complementarities and productive public expenditure, we analyse theoretically the growth effects of an increase in productive public expenditure, which we find positive in the short, medium and long run.     

Public Sector Organizations and Cocreation With Citizens: A Literature Review on Benefits,Drivers, and Barriers

ABSTRACT

Cocreation has captured the attention of public managers and policymakers and yet the literature focusing in the public sector is still relatively dispersed. In this literature review we present a contextualized analysis of the potential reasons that lead public sector organizations to cocreate with citizens and identify potential barriers that may hamper the adoption of cocreation in public settings. The analysis undertaken allowed us to conclude that the topic is increasingly capturing the interest of researchers, although the state of the literature is characterized by a reduced heterogeneity in research methods. We classified cocreation benefits in the public sector as innovation related, improved decision-making, and symbolic related, and we categorized the drivers for cocreation according to three broad categories: external, relation-specific and internal. Finally, we identified potential barriers of cocreation, including structural, organizational, and behavioral barriers.     

Managers and Wage Policies

Do individual top managers matter for wages and wage policies? Are there general differences in “style” among managers with respect to worker compensation? To shed light on these questions, we exploit a large panel dataset from Portugal that allows us to match workers, firms, and managers, and follow the movements of the latter across different firms over time. While accounting for the effect of worker and firm heterogeneity, we estimate the role of top manager fixed effects in determining wages and wage policies. The estimates suggest that (i) top managers have a significant influence on wages and wage policies; (ii) there exists different managerial “styles”; and (iii) managers’ (observable) attributes matter for worker compensation.     

What Initiatives Are British Food Retailers Taking to Improve Children’s Health and Nutrition?

Along with food manufacturers, retailers contribute directly to the national diet. While efforts to reformulate private-label products have been assessed, little research considers other voluntary initiatives to impact public health. We explore efforts targeting children’s health and nutrition. Making use of the corporate social responsibility reports of the seven leading retailers from 2006 to 2011, we examine the types of actions, by which retail chains and when. Before 2008, most retailers reported on initiatives promoting children’s nutrition education and physical activity in schools. Since 2009, references to such programs have decreased, with a shift toward child wellness. We find that retailers differ in approaches and commitment. Those with larger market shares mention initiatives more frequently. Most activities are related to nutrition education, developing cooking skills, and promotion of physical activity and not product reformulation. Our research suggests these efforts are not coordinated, might be misplaced, and do not persist over time.     

Counterfactual analysis of bank mergers

We introduce a counterfactual analysis of banks mergers, combining the pre-merger equilibrium setting with post-merger environmental characteristics, while accounting for endogenously propagated changes in market structure. Using this procedure we are able to estimate the effects on loan flows and interest rates that would have been observed if the pre-merger equilibrium was not altered. Results are obtained for firms, households, and banks inside and outside the merging circles separately. We find that mergers increased firms’ access to credit, but had an opposite effect on households and led to a widespread decrease in interest rates.     

EU Enlargement and the Portuguese Economy

The main focus of the present paper is on the emerging and likely future trade effects of enlargement. Though our particular concern is with Portugal, we set the scene by comparing the trade structures of the 10 countries of Central and Eastern Europe (i.e. the eight CEE accession states plus Bulgaria and Romania) – including an analysis of the individual cases of the Czech Republic, Hungary and Poland – with those of the EU15 as a whole, and with those of the 4 EU cohesion countries. The elimination of trade barriers between incumbents and accession states will have two trade‐related effects on EU incumbents: an increase in bilateral flows with the CEEC and a shift effect as the CEEC displace some incumbent exports to EU markets. The first effect is likely to be strongest for those incumbents for which there is a strong overlap between their export structure and the import structure of the CEEC. Portugal emerges as one of the economies with the least overlap. The displacement effect, we conclude, is likely to be particularly strong in the case of Portugal, given the high degree of similarity between Portuguese exports and those of the CEEC. Portugal appears to be ‘being squeezed from below’ in that, for the majority of its traditional export sectors, the CEEC became progressively more competitive during the second half of the 1990's. Portuguese specialisation was increasingly confined to low‐technology, low‐added‐value sectors with declining demand, as strong FDI inflows to the CEEC led to an increasing preponderance of more dynamic sectors in their export structures. Thus, Portugal is also being squeezed from above. This suggests that there may be substantial industrial disruption, in response to which labour‐market flexibility and dynamic entrepreneurial response is crucial. Intersectoral mobility is generally easier the more highly educated the workforce – an indicator on which Portugal scores poorly. The Portuguese labour market, however, displays a high degree of flexibility, consistent with its long lasting low rate of unemployment. Continued flexibility will help minimise these likely adjustment costs. Besides the trade and industry effects, other topics considered in the paper include the implications of enlargement for Portugal's ability to attract FDI, the likely consequences for Portugal of inward migration from the CEEC to the EU, and the implications of enlargement for Portugal's budgetary relations with the rest of the EU.
