Analysing pollution by way of vertically integrated coefficients, with an application to the water sector in Aragon

In this paper, we adopt Pasinetti's approach of vertically integratedsectors in order to disaggregate pollution into its most significantcomponents. Vertical integration allows us to obtain five components(and at least five measurement indices) corresponding to eachsector and each type of pollution. These indices overcome someof the deficiencies of the traditional Rasmussen-type coefficients.The empirical application is carried out by reference to thewater sector in Aragon, a region which lies in north-easternSpain, for five polluting factors, namely: water returns, biologicaloxygen demand at five days (BOD5), suspended solids (SS), nitratesand phosphates.     

The nexus between firm-supply-chain relationships and the potential for tourism development: A case study approach

This exploratory study examines the importance of firm-supply chain relationships for tourism development. Based upon prior observations, two firms seeking to boost their tourism offerings and operating in a popular Vietnamese tourist destination were selected. Semi-structured face-to-face and online interviews were conducted and complemented by on-site visits, and firm information. Various salient dimensions emerged from the data analysis. The ‘performance catalyst’ and ‘detectable value adding’ dimensions underscore the supply chain's benefits, while the ‘discerning relations’ dimension highlights deeper relationships through mutual support, building trust, or demonstrating care. Conceptually, the study proposes a framework with associated theoretical and practical implications.     

The Main Determinants of the Use of the Cost Accounting System in Portuguese Local Government

Abstract: This paper explores the main determinants of the use of the cost accounting system (CAS) in Portuguese local government (PLG). Regression analysis is used to study the fit of a model of accounting changes in PLG, focused on cost accounting systems oriented to activities and outputs. Based on survey data gathered from PLG, we have found that the use of information in decision‐making and external reporting is still a mirage. We obtain evidence about the influence of the internal organizational context (especially the lack of support and difficulties in the CAS implementation) in the use for internal purposes, while the institutional environment (like external pressures to implement the CAS) appears to be more deterministic of the external use. Results strengthen the function of external reporting to legitimate the organization's activities to external stakeholders. On the other hand, some control variables (like political competition, usefulness and experience) also evidence some explanatory power in the model. Some mixed results were found that appeal to further research in the future. Our empirical results contribute to understand the importance of interconnecting the contingency and institutional approaches to gain a clear picture of cost accounting changes in the public sector.     

Reputational recovery under political instability: Public debt in Portugal, 1641–83

This article examines the reputation recovery of Portugal's public debt during the war of liberation against the former Habsburg ruler. Using novel datasets on long- and short-term debt and nominal interest rates, this study provides evidence that the sovereign borrower used debt credibility to build a pact of regime in a revolutionary context with implications for financing the war. The Portuguese kings followed an implicit budget balance rule as a reputational scheme, which made Portugal an exceptional case of military success with a low debt-to-GDP ratio and low interest rates. These conclusions contribute to the literature in various attributes of war finance, debt management, and state-making by showing that default avoidance could be as important to military success as fiscal capacity.     

When transparency pays off: Enticing sceptical consumers with two-sided advertising

It has been generally assumed that higher levels of scepticism towards advertising invariably lead to higher resistance to advertising appeals. The main purpose of the present research was to examine whether highly sceptical consumers' resistance can be overcome by appeals associated with higher credibility. We tested our hypotheses using message sidedness as an advertising variable that has been associated with higher (two-sided) versus lower (one-sided) credibility. In three experimental studies, we examined more versus less sceptical consumers' responses to two- versus one-sided appeals. We found that two-sided messages are more effective in increasing purchase intentions, through enhanced credibility, but only for consumers who are more sceptical of advertising. Less sceptical consumers trust both messages equally and their purchase intentions are not affected by the type of message. Importantly, we also showed that highly sceptical consumers trust two-sided appeals as much as their less sceptical counterparts. The study contributes to the literature on advertising and persuasion knowledge by showing that advertising scepticism does not elicit a single response tendency, as originally conceptualized. Rather, advertising scepticism is more consistent with the underpinnings of the Persuasion Knowledge Model, in that higher knowledge about persuasion tactics aids consumers to better cope with, and not invariably resist persuasion attempts. We conclude that transparency pays off because it may entice a more sceptical audience and, at the same time, it does not harm less sceptical consumers' trust and purchase intentions.     

Sensory characteristics of fufu prepared with cassava roots (Manihot esculenta Crantz) stored in polyethylene sacks

This study was carried out to assess the effect of storage of cassava roots in polyethylene sacks for periods of 2, 4, 6 and 8 weeks on the sensory characteristics of cassava fufu, a popular Ghanaian dish. Freshly harvested cassava roots were dipped in tap water and packed into polyethylene sacks in 2‐kg batches and stored at room temperature (25°C ± 1°C). Samples of fresh cassava fufu were evaluated and then at two weekly intervals for a period of 8 weeks. Attributes evaluated were colour, smell, elasticity, smoothness and taste. A structured six‐point ranking scale ranging from 6 (excellent) to 1 (very poor) was used for the evaluation. The data were analysed using analysis of variance, and the least significance difference test at P < 0.05 was used to determine differences between means. The results showed that storage of cassava roots for up to 8 weeks did not significantly affect the colour, smell, elasticity and taste of cassava fufu. However, smoothness of fufu prepared with cassava stored for 6 and 8 weeks was significantly different from the samples of the fresh cassava, and those stored for 2 and 4 weeks. It was concluded that cassava roots stored for periods up to 8 weeks in polyethylene sacks produced fufu of similar characteristics as fresh cassava fufu. This method is therefore recommended for use by homemakers, food service operators, cassava retailers and processors to save them time, energy and money used for the frequent trips for purchases. The method would also reduce post‐harvest losses to a large extent.     

A regional perspective on inequality and growth in Portugal using panel cointegration analysis

This paper examines the relationship between inequality and economic growth for thirty Portuguese NUTS3 regions within a multivariate panel framework over the period 1995–2007, using panel cointegration techniques to test for the existence of a relationship between inequality and real GDP per capita. The results point to the existence of a relationship between the variables, where the effect of inequality, measured as the Gini index of the earnings distribution, on per capita output is negative. This negative influence seems to be determined by the behaviour of the bottom of the earnings distribution, most likely by dampening investment in human capital, with the results pointing to the coexistence of a positive impact of inequality at the top of the distribution, supporting the incentives argument for the inequality-growth nexus. Additionally, the results confirm the predicted positive relationship between human capital and output, lending support to both the exogenous and endogenous growth models predictions on the importance of human capital for production both as an input in the production of final goods and in the production of technology. Another interesting result concerns structural funds: we found a negative relation of this variable with regional output. We believe that EU structural funds were a source of Dutch disease for Portugal, which resulted mainly in a lack of external competitiveness of the Portuguese economy due to the excessive specialization in non-tradable goods made possible by the European funds.     

Should special agricultural safeguard be ignored? An evaluation for dairy trade

This study measured the impact of special agricultural safeguards (SSG) on dairy products imports by the US and Japan. It was observed that dairy products have been the most affected by this protectionist measures, and that these countries are relevant importers that impose SSG. The tariff lines subject to SSG were selected, and the period of analysis was from 1995 to 2015. The results showed that the impact of SSG applied by the US was much higher than for Japan. The overall estimated value of imports that did not happen due to the application of SSGs was approximately USD 2 billion. Specifically for the Brazilian economy, the condensed milk not exported to the US due to SSG applied cost the country BRL 345 million in GDP value and almost 4.5 thousand jobs. These results might be underestimating these effects, since the SSG tariff was not subject to calculation in several years.
