Re-Recognition of Ride-Sourcing Service: From the Perspective of Operational 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.

A New Approach to Inflation through the Joint Analysis of Economics Efficiency and Social Welfare. A case study: Argentina

This paper points out the main e1ements under analysis in a study aimed at bringing out the relevant causes of inflation in each kind of economic structure. Thus, it stresses the necessity of a direct answer to questions like when, where, why and how an inflationary process is generated as well as its economic, political and social consequences. Further, it points out the necessity of analyzing the nature of inflation and its circumstances rather than contrasting structuralism vs. monetarism. Thus it seeks to specify the causes of inflation, their direction, intensity and interaction in a given type of economic and social structure. With that aim the ideas of economic efficiency and social welfare are introduced and applied to an interpretation of the Argentine case during the last hundred years.

Is Ride-sourcing Service Really Sustainable : Operational Efficiency and Social Welfare Analysis Through an Equilibrium Model

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.

Can developing countries benefit from export promotion?

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.
