Unlock the Sharing Economy: The Case of the Parking Sector for Recurrent Commuting Trips

This study examines the pricing strategy of a parking sharing platform that rents the daytime-usage rights of private parking spaces from parking owners and sells them to parking users. In an urban area with both shared parking and curbside parking, a choice equilibrium model is proposed to predict the number of shared parking users under any given pricing strategy of the platform. We analytically analyze how the pricing strategy of the platform (price charged on users and rent paid to parking owners or sharers) would affect the parking choice equilibrium and several system efficiency metrics. It is shown that the platform is profitable when some parking owners have a relatively small inconvenience cost from sharing their spaces, but its profit is always negative at minimum social cost. Numerical studies are conducted to illustrate the analytical results and provide further understanding.

Imperfect Competition, Compensating Differentials, and Rent Sharing in the US Labor Market

We quantify the importance of imperfect competition in the US labor market by estimating the size of labor market rents earned by American firms and workers. We construct a matched employer-employee panel dataset by combining the universe of US business and worker tax records for the period 2001–2015. Using this panel data, we identify and estimate an equilibrium model of the labor market with two-sided heterogeneity where workers view firms as imperfect substitutes because of heterogeneous preferences over nonwage job characteristics. The model allows us to draw inference about imperfect competition, worker sorting, compensating differentials, and rent sharing. (JEL D24, H24, H25, J22, J24, J31, J42)

Research on the Evolution Path of China’s Provincial Innovation Chain Model Based on Complex Network Model

By constructing a complex network analysis model, this paper analyzes the data of 31 selected provinces in China from 2010 to 2019, summarizes China’s provincial innovation chain development model, and then combined with the time series analyzes the evolution path of the model. The research shows that there is certain group proximity in China’s provincial innovation chain in each year, and there are eleven models in ten years. The evolution path of the provincial innovation chain development model is mainly manifested in the development trend of low-level to medium-level and then high-level equilibrium model. Increasing investment and improving efficiency are the leading driving force for the development of China’s provincial innovation chain. The medium-level equilibrium model runs through almost all years. Taking this as the node, the innovation driving force gradually changes from high investment to high efficiency.

Impact of Exports on the Exporter’s Domestic Market

This paper developed a theoretical model of partial equilibrium of the export-oriented market for a short-term period, as well as outlined the main approaches to modeling equilibrium in a long-term period. Thus, the competition between the producers of the selected exporting country and its global competitor in the external import-dependent market is considered. In the partial equilibrium model, for the first time, the domestic and foreign sales markets are presented together. The analysis of the theoretical model made it possible to obtain the following results for the short-term period: in a state close to equilibrium, external supplies of the exporting country are positively related to their own production volumes and negatively – ​with the production volumes of the global exporter; the price of the domestic market of the exporting country is negatively related to the volume of its own production and the volume of production of the global exporter. The paper analyzes three scenarios that allow checking the adequacy of the partial equilibrium model for different conditions of its application. The first scenario considers a negative supply shock associated with a drop in production in a global exporter. The second analyzes the impact of the pandemic on the global exporter and exporting country. The third scenario is devoted to assessing the impact of a demand shock on a designated exporting country. The scenarios confirmed the adequacy of the model. The approach to modeling an export-oriented market for a long-term period is based on the assumption that the exporter's price will converge with the price of the domestic market over time and, ultimately, will differ from it only by the amount of additional costs associated with the export of a unit of production. It was established that, while maintaining exogenous conditions for positive long-term export dynamics, the price of the domestic market of the exporting country will decrease in case of an increase in the incremental values of exports and production volumes of the global exporter. The consequences of the positive dynamics of exports for the domestic demand of the exporting country are considered. The established relationships between exports and sales in the exporter's domestic market were empirically confirmed by the example of the Russian sunflower oil market.
