On the social value of publicly disclosed information and environmental regulation

2018

Abstract This paper presents an analysis of environmental policy in imperfectly competitive market with publicly disclosed and privately-held information about costs. We examine the potential asymmetry-reducing role of disclosure and its impact on setting environmental taxes. From a policy perspective, our findings show that disclosure with verifiable reports, is a valuable public good, provides greater transparency in the market, and is generally efficiency enhancing. Results suggest that access to publicly disclosed information enables the fine-tuning of the tax rules towards specific environmental circumstances and improves the ability of the regulator to levy firm-specific environmental…

Are Audit Firms’ Compensation Policies Associated With Audit Quality?

2020

We examine how compensation policies of audit firms are associated with audit quality. Specifically, we investigate the effects of the ratio of variable to fixed compensation and the size of the basis for profit sharing (i.e., whether partners share profits in a small or in a large profit pool). For our analyses, we use detailed mandatory disclosure of the compensation policies in German audit firms. We document that compensation policies vary considerably across audit firms. We find that profit sharing in a small profit pool and high variable compensation are two characteristics of auditor compensation associated with lower audit quality. We also find some evidence suggesting that audit qu…

Sharing economy and incumbents' pricing strategy: The impact of Airbnb on the hospitality industry

2019

Abstract In this paper, we examine how the emergence of sharing economy platforms influences incumbents' price responses. Grounding on the literature on price reactions to new entrants and on the unique characteristics of the sharing economy, we argue that the effect of the penetration of the sharing economy on incumbents' prices is not straightforward, and actually depends on the type of incumbents as well as certain product/service offer characteristics. Indeed, relying on a large sample of hotel price offerings from the Italian market, we find that the effect of the growing relevance of the sharing economy (exemplified by Airbnb) on incumbents' prices depends on the type of incumbents (l…

Sharing economy and dynamic pricing: Is the impact of Airbnb on the hotel industry time-dependent?

2021

Abstract Prior literature has reported significant price and revenue reductions in the hotel industry due to the emergence of Airbnb. Other studies have documented that hotels' price reactions to the penetration of Airbnb depend on their service level, e.g., low/medium-end versus high end. Relying on a large sample from the Italian market, we contribute by showing that the effect of Airbnb on hotels' price decisions does not only depend on incumbents’ quality level, but also on the difference between booking and check-in time. That is, the effect of the penetration of Airbnb on hotels' dynamic price decisions varies over time depending on the core segment hotels target.

Online optimization of a multi-conversion-level DC home microgrid for system efficiency enhancement

2017

In this paper, an on-line management system for the optimal efficiency operation of a multi-bus DC home distribution system is proposed. The operation of the system is discussed with reference to a distribution system with two conversion stages and three voltage levels. In each of the conversion stages, three paralleled DC/DC converters are implemented. A Genetic Algorithm performs the on-line optimization of the DC network’s global efficiency, generating the optimal current sharing ratios of the concurrent power converters. The overall DC/DC conversion system including the optimization section is modelled using MATLAB/Simulink. Thanks to the implemented online algorithm, considering …

Market Opportunity of China Telecom 3G Toward 4G - A Social-Technical Analysis for its Future Development

2013

In the Information and communication Technology (ICT) field, the success a new player will face is the challenge for the opportunity of new market development. China's mobile subscribers grew by 9.93 millions to 1.132 billions in February 2013.The convenience of communication prompted China’s growth, but there is little information available in literature about how it happened and what the next development steps will be for the China Telecom Industry.The purpose of this paper is an attempt to picture the future growth path of China Telecom market opportunities from 3G toward 4G and beyond, including viewing this from the angles of telecom/internet e-commerce regulation development; globaliz…

Current-Sensing Technique for Current-Mode Controlled Voltage Regulator Modules

2008

This paper introduces an innovative current-sense technique for voltage regulator modules (VRMs). The proposed method is applied to a multiphase buck converter although the converter topology does not affect the accuracy or effectiveness of the proposed technique. A RC network is parallel connected with the buck converter low-side MOSFET and the voltage signal across the sense capacitor reconstructs the inductor current waveform. The RC technique benefits from all the advantages of the most popular current-sensing technique, the inductor DC resistance current-sense method, cutting off its main disadvantage. The sense network design is oriented to obtain high immunity to noise and a great dy…

Active load sharing technique for on-line efficiency optimization in DC microgrids

2017

Recently, DC power distribution is gaining more and more importance over its AC counterpart achieving increased efficiency, greater flexibility, reduced volumes and capital cost. In this paper, a 24-120-325V two-level DC distribution system for home appliances, each including three parallel DC-DC converters, is modeled. An active load sharing technique is proposed for the on-line optimization of the global efficiency of the DC distribution network. The algorithm aims at the instantaneous efficiency optimization of the whole DC network, based on the on-line load current sampling. A Look Up Table, is created to store the real efficiencies of the converters taking into account components toler…

In order to improve the market value of the product, the platform enterprise often participates in the development process of supporting product of emerging industry’s platform innovation ecosystem. This paper puts forward a revenue sharing contract between the platform company and the supporting company by creating a collaborative development model of the supporting product in the ecosystem, and this paper studies the platform enterprise investment resource property's (complementary or substitution) impact on the supporting enterprise R&D efforts and the revenue sharing factor and analyzes collaborative development mechanism of supporting product of emerging industry platform innovatio…

The Impacts of ICT Support on Information Distribution, Task Assignment for Gaining Teams’ Situational Awareness in Search and Rescue Operations

2015

Information and Communication Technology (ICT) has changed the way we communicate and work. To study the effects of ICT for Information Distribution (ID) and Task Assignment (TA) for gaining Teams’ Situational Awareness (TSA) across and within rescue teams, an indoor fire game was played with students. We used two settings (smartphone-enabled support vs. traditional walkietalkies) to analyze the impact of technology on ID and TA for gaining TSA in a simulated Search and Rescue operation. The results presented in this paper combine observations and quantitative data from a survey conducted after the game. The results indicate that the use of the ICT was good in second scenario than first sce…
