Afghanistan's New Vat, Part 1: Invoice Matching Or A Unitary Digital Invoice, Richard Thompson Ainsworth, Musaad Alwohaibi, Andrew Leahey, Yujin Li, Haseena Rahman

Faculty Scholarship

In the summer of 1990 two groundbreaking articles on business process re-engineering (BPR) were published, one by Thomas H. Davenport (a professor in information technology at Babson College) in the MIT Sloan Management Review, the other by Michael Hammer (a professor of computer science at MIT) in the Harvard Business Review. BPR is a management strategy that analyzes IT-intensive workflow designs and business processes within an organization.

On December 21, 2020 (Jadi 1, 1399) Afghanistan was scheduled to implement a 10% VAT. It has been delayed one year by the pandemic. When it does implement, Afghanistan will have significant workflow …

Information Technology And Industry Concentration, James Bessen

Faculty Scholarship

Industry concentration has been rising in the US since 1980. Firm operating margins have also been rising. Are these signs of declining competition that call for a new antitrust policy? This paper explores the role of proprietary information technology systems (IT), which could increase industry concentration and margins by raising the productivity of top firms relative to others. Using instrumental variable estimates, this paper finds that IT system use is strongly associated with the level and growth of industry concentration and firm operating margins. The paper also finds that IT system use is associated with relatively larger establishment size and …

Error Costs, Ratio Tests, And Patent Antitrust Law, Keith N. Hylton, Wendy Xu

Faculty Scholarship

This paper examines the welfare tradeoff between patent and antitrust law. Since patent and antitrust law have contradictory goals, the question that naturally arises is how one should choose between the two in instances where there is a conflict. One sensible approach to choosing between two legal standards, or between proof standards with respect to evidence, is to consider the relative costs of errors. The approach in this paper is to consider the ratio of false positives to false negatives in patent antitrust. We find that the relevant error cost ratio for patent antitrust is the proportion of the sum …

Incentives To Take Care Under Contributory And Comparative Fault, Keith N. Hylton, Benjamin Ogden

Faculty Scholarship

Previous literature on contributory versus comparative negligence has shown that they reach equivalent equilibria. These results, however, depend upon a stylized application of the Hand Formula and an insufficiently coarse model of strategic incentives. Taking this into account, we identify a set of cases where care by one agent significantly increases the benefits of care by the other. When such cases obtain under bilateral harm, comparative negligence generates greater incentives for care, but this additional care occurs only when care is not socially optimal. By contrast, under unilateral harm or asymmetric costs of care, contributory negligence creates socially excessive care. …

Externalities And The Common Owner, Madison Condon

Faculty Scholarship

Due to the embrace of modern portfolio theory, most of the stock market is controlled by institutional investors holding broadly diversified economy-mirroring portfolios. Recent scholarship has revealed the anti-competitive incentives that arise when a firm’s largest shareholders own similarly sized stakes in the firm’s industry competitors. This Article expands the consideration of the effects of common ownership from the industry level to the market-portfolio level, and argues that diversified investors should rationally be motivated to internalize intra-portfolio negative externalities. This portfolio perspective can explain the increasing climate change related activism of institutional investors, who have applied coordinated shareholder power to …

Declining Industrial Disruption, James Bessen

Faculty Scholarship

Recent research finds that markups are rising, suggesting declining competition. But does less price competition mean less Schumpeterian “creative destruction”/industry dynamism? This paper reports the first recent estimates of trends in the displacement of industry-leading firms. Displacement hazards rose for several decades since 1970 but have declined sharply since 2000. Using a production function-based model to explore the role of investments, acquisitions, and lobbying, we find that investments by dominant firms in intangibles, especially software, are distinctly associated with greater persistence and reduced leapfrogging. Software investments by top firms soared around 2000, contributing substantially to the decline. Also, higher markups …

Response To Oliar And Stern: On Duration, The Idea/Expression Dichotomy, And Time, Wendy J. Gordon

Faculty Scholarship

Courts often use possession to determine who should own unclaimed resources. Yet, as Oliar and Stern demonstrate, the concept of possession is little more than a metaphor, capable of being applied to a broad range of phenomena. The authors helpfully deploy “time” as a metric to sort through the rules determining what should count as possession, and they survey the likely costs and benefits attached to choosing earlier versus later events as triggers for acquiring title.

With those tools in hand, Oliar and Stern employ “time” and the analogy of physical possession to address problems in copyright, patent, and trademark …
