PurposeAlthough economic theory generally does not support government intervention in international trade, casual observation shows that many developing countries adopt certain trade policies to promote their exports. The objective of this paper is to answer the question that whether developing countries can benefit from export promotion.Design/methodology/approachThis paper considers a developing country which has to import new technology from the world market to improve its productivity. If it has certain economic rigidities, the country is short of foreign exchange and domestic firms cannot import an adequate amount of new technology. Even if there is no rigidity, domestic firms may not have sufficient incentive to invest in new technology. Therefore, the government can step in to subsidize exports. Through an analytical model, this paper investigates in what conditions the measures of export promotion can stimulate production and employment, and improve efficiency and social welfare.FindingsThis paper analyzes two effects of export promotion: raising the incentive of capital investment and reducing capital goods shortage caused by foreign exchange constraint. These effects might be the economic rationale for developing country governments to promote exports. It is found that export promotion can definitely raise employment and productivity, but whether these measures can stimulate the supply to the domestic market and improve domestic welfare depends on the sufficient and necessary condition given in the paper.Originality/valueEstablishes an analytical model to investigate in what conditions the measures of export promotion such as export subsidies and domestic currency devaluation can stimulate production and employment, and can improve efficiency and social welfare.

With increasing availability of alternative mobility options for city transportation system, it is necessary to better understand how emerging mobility options are impacting the travel demand and consumer-social surplus. However, few study have been conducted to evaluate the social welfare effects of the range of vacant trips in ride-sourcing service modes. This paper identified the vacant trip and loading rate evaluation model under the ride-sourcing service mode to enhance the effective operation of the different mobility services under numerical illustrations. The solution can also offer some beneficial guidance and theoretical basis for ride-sourcing systems in regard to planning and management aspects.

This paper presents a method using nodal pricing for optimal allocating distribution generations (DG) for profit maximization, reduction of loss in distribution network along with social welfare maximization. Inclusion of distributed generation (DG) resources in power system changes the power flows and the magnitude of network losses at the distribution side. A detailed analysis has been simulated in MATLAB with 33 bus distribution system. The Genetic algorithm optimization is used in this work to find optimal location and size of DG in radial distribution system. Applying nodal pricing to a model distribution network, it shows significant price differences between buses reflecting high marginal losses and by finding optimal size of DG maximizes the profit of distribution companies that use DG in their networks for obtaining multiple benefits.

With increasing availability of alternative mobility options for city transportation system, it is necessary to better understand how emerging mobility are impacting the travel demand and consumer-social surplus. However, few study has been conducted to evaluate the social welfare effects of the range of vacant trip in mobility oriented development(MOD) mode. This paper identified the vacant trip and loading rate evaluation model under mobility oriented development mode. recommended solutions to enhance the effective operation of the different mobility services under numerical illustrations, which can offer some beneficial guidance and theoretic basis to the efficiency of MOD in planning and management aspects.
