A solution to the Lucas–Uzawa model with increasing returns to scale: Note

Chilarescu [2008, An analytical solutions for a model of endogenous growth, Economic Modelling.] claims that he determines a solution path to the Lucas–Uzawa model with increasing returns to scale. However, the path is not a closed-form since it depends on the initial consumption and the initial time for goods production, that are unknown. Moreover, the production function is nonconcave and then the first order conditions and the transversality conditions are not sufficient for the optimality. This note converts the model to a problem in which the Hamiltonian is available and derives a fully-closed form solution.     

Trust and development

In this paper we examine linkages between social trust and economic development using, for the first time, a panel of data. We confirm earlier cross-sectional studies finding that trust is a significant factor in development and also show for the first time that trust significantly interacts with both investment in physical and human capital. We provide a robustness analysis of our results via a set of jackknife experiments on our main equations, and the trust coefficients and interactions are very tightly distributed, indicating that the results are not highly sample dependent. We also consider whether trust directly influences investment and find that in a panel framework it does not unless we allow for a trust–education interaction in the investment equation.     

Urban vs. rural destinations: Residents’ perceptions,community participation and support for tourism development

This paper investigates and compares the effects of residents' perceptions of the impacts of tourism on community participation and support for tourism development across urban and rural world heritage sites (WHSs). Partial least squares – structural equation modeling (PLS-SEM), has been employed to perform the analysis. The results reveal significant differences between the effects of residents' perceptions and community participation on support for tourism development in urban and rural destinations. However, the findings did not support any differences between the effects of positive perceptions on community participation, and the indirect effects of negative perceptions on support for tourism development. This study makes a significant theoretical contribution to the urban and rural tourism and residents’ perceptions literature by comparing rural and urban WHSs residents. Furthermore, this study has a number of practical implications for the local authorities of rural and urban WHSs.     

Methodology to calculate the carbon footprint of household land use in the urban planning stage

The growing concerns of climate change require implementing measures to quantify, to monitor and to minimize greenhouse gas (GHG) emissions. Nonetheless, most of the measures available are not easy to define or execute because they rely on current emissions and have a corrective character. To address this issue, a methodology to characterize GHG emissions that allows implementing preventive measures is proposed in this paper. The methodology is related to household urban planning procedures and considers urban infrastructures to characterize GHG emissions and to execute preventive measures based on sustainability design criteria. The methodology has been tested by applying it to a set of medium-sized municipalities with average GHG emissions from 6,822.32 kgCO_2eq/year to 5,913.79 kgCO_2eq/year for every residential unit. The results indicate that the greatest pollutant source is transport, especially in the issuance of street network design, followed by gas and electricity consumption. The average undevelopable land area required for the complete GHG emissions capture amounts to 3.42 m² of undevelopable land for every m² of urbanizable land and 9.02 m² of undevelopable land for every m² of built land.     

Is the development of the agro-processing industry pro-poor?: The case of Thailand

We examine how the development of the agro-processing industry contributed to poverty reduction in Thailand. The effects on farmers’ income are emphasized because most of the poor in Thailand are farmers. The development of the agro-processing industry could improve farmers’ income through two channels: (i) the purchase of agricultural products; and (ii) the employment of the poor farmers at factories. We show that the development of the agro-processing industry, which also played a leading role in the high economic growth of the Thai economy, contributed to poverty reduction through both of the two channels. It was hence pro-poor.
