Media firms sometimes allow consumers to pay to remove advertisements from an ad-based product. We formally examine an ad-based monopolist's incentives to introduce this option. When deciding whether or not to introduce the option to pay, the monopolist compares the potential direct revenues from consumers who pay, with the lost advertising revenues resulting from the subsequent ad removal. If the
We discuss network neutrality regulation of the Internet in the context of a two-sided market model. Platforms sell broadband Internet access services to residential consumers and may set fees to content and application providers on the Internet. When access is monopolized, cross-group externalities (network effects) can give a rationale for network neutrality regulation (requiring zero fees to co
Private equity firms are often criticized for laying off workers, but the evidence on who loses their jobs and why is scarce. This paper argues that explanations for job polarization also explain layoffs after private equity buyouts. Buyouts reduce agency problems, which triggers automation and off shoring. Using rich employer-employee data, we show that buyouts generally do not affect unemploymen
We establish a correlation between the hierarchical structure of a firm and the likelihood of business creation among its former employees, using a sample of 16 million observations of Swedish workers and a novel proxy for hierarchies based on occupation data. Conditional on firm size and many other variables, employees in firms with more layers are less likely to enter entrepreneurship, to become
An increasingly large share of cross-border acquisitions are undertaken by private equity-firms (PE-firms) and not by traditional multinational enterprises (MNEs). We propose a model of cross-border acquisitions in which MNEs and PE-firms compete over domestic assets and which incorporates endogenous financial frictions. MNEs’ advantages lie in firm-specific synergies and access to internal capita
The authors cast entrepreneurship as one of three career choices—remaining with one’s employer, changing employers, or engaging in entrepreneurship—and theorize how the likelihood of entrepreneurship evolves over one’s career. They empirically demonstrate an inverted U-shaped relationship between accumulated experience and entrepreneurship across various industries and jobs. The authors highlight
The media often cast foreign private equity firms as villains who gamble with local jobs. We use detailed registry data from Sweden to show that foreign buyouts have not affected workers’ labor market outcomes. But domestic buyouts have. They have increased unemployment incidence by a fifth, duration by a third, and lowered labor income by seven percent.
In recent years, the number of listed companies has been declining in many countries across the world. This paper provides a selective survey of the literature on the real economic effects of the stock market to assess the potential effects of this decline and determine whether it is likely to continue. The leading economic role of the stock market's primary market, in which firms raise capital by
Private equity firms (PE firms) have become common owners of established firms in concentrated markets. We show that the threat of a PE acquisition can trigger incumbent mergers in an otherwise merger-stable industry. This can help antitrust authorities maximize consumer surplus because previously privately unprofitable – but consumer surplus-enhancing – mergers now take place. We thus predict tha
This article analyzes the real effects of private equity buyouts. It defines private equity buyouts as gains of established companies accepted by private equity firms. Private equity buyouts are also referred to as leveraged buyouts, management buyouts, and bootstrap acquisitions. The first section explains why buyouts have real economic effects, while the second section presents a survey of empir
We survey the literature on venture capital and institutions and present a case study comparing the development of the venture capital market in the United States and Sweden. Our literature survey underscores that the legal environment, financial market development, the tax system, labor market regulations, and public spending on research and development correlate with venture capital activities a
The tax laws of most developed countries are debt biased since firms can deduct interest on debt but not on equity. This bias is known to distort investment decisions. However, less is known about how the debt tax shield affects the ownership of assets when bidders differ financial expertise and thus in optimal use of leverage. We show that the debt tax shield need not always distort ownership eff
Using a dataset with over 24 million year-employment observations and the universe of more than 230,000 entries into entrepreneurship in one economy we analyze the gross (including the founders), net (excluding the founders), and new (jobs to the former unemployed or those outside the labor force) job creation by entrepreneurs two and six years after start-up. These novel measures of job creation
I study the internal organization of firms using Swedish occupation data. The empirical patterns match the theoretical predictions of Caliendo and Rossi-Hansberg (2012) and are similar to the patterns observed in French data by Caliendo etal. (2012).
In industries with network effects, incumbents' installed bases create barriers to entry that discourage entrepreneurs from developing new innovations. Yet, entry is not the only commercialization route for entrepreneurs. We show that the option of selling to an incumbent increases the innovation incentives for entrepreneurs when the network effects are strong and incumbents compete to preemptivel
We extend the workhorse model of network competition to international calls. This model enables us to show that national regulatory authorities (NRAs) maximizing domestic welfare have incentives to increase termination rates above the social optimum to extract rent from international call termination. Excessive termination rates distort prices but transfer surplus from foreign to domestic consumer
Purpose: To address the systematic bias in whole-brain dual flip angle (DFA) T1-mapping at7T by optimizing the flip angle pair and carefully selecting RF pulse shape and duration.Theory and Methods: Spoiled gradient echoes can be used to estimate whole-brain maps ofT1. This can be accomplished by using only two acquisitions with different flip angles, i.e., aDFA-based approach.
