We develop a model of competition in prices and infrastructure among mobile network operators. Consolidation can increase market power, but economies of scale, which we derive from physical principles, lead to more efficient data transmission. Estimating our model with French consumer and...

This dissertation investigates the emergence of the Frequent Batch Auction (FBA) as a new auction mechanism for financial exchanges. It aims to explore the performance of academically established algorithms, previously examined in Continuous Double Auctions, when simulated in an FBA. To achieve...

In the governance of the shared mobility market of a city or of a metropolitan area, there are two conflicting principles: 1) the healthy competition between multiple platforms, such as between Uber and Lyft in the United States, and 2) economies of network scale, which leads to higher chances...

Conditions under which spectrum is allocated are significant in determining the market structure in the telecom sector which in turn affects the prices and the quality of mobile services. In a more concentrated market, the quantity of spectrum is less diluted, and operators can offer higher...

We propose a data-based approximation of the effects of trade sanctions. We validate the approximation by comparing it with exact responses simulated from a canonical multi-country multi-sector model. The approximation is palatable for a broad range of elasticities of substitution, except for...

We develop high-frequency indexes to measure sales in service industries and production in the manufacturing sector by using GPS mobility data from mobile applications. First, by utilizing the point of interest data, we develop indicators to capture sales in amusement parks, shopping centers,...

Adaption of the new technology is a prerequisite for the business's survival and to meet the quality standard. The public address system is widely used in all areas of living; it helps the host speaker to easily disperse the desired messages. This study aimed to develop a wireless digital...
