Carrier aggregation and integration of heterogeneous networks allow the mobile user equipment to benefit from wider bandwidth and radio coverage of different access technologies. However, these technologies have increased handoff scenario probability through user equipment's mobility, leading to...

Does macroeconomic uncertainty increase or decrease aggregate growth and asset prices? To address this question, we decompose aggregate uncertainty into ‘good' and ‘bad' volatility components, associated with positive and negative innovations to macroeconomic growth. We document that in line...

When faced with a big problem, it is natural to summarize the data en route to a solution. But accepting summary as fact gives up evidence for convenience. Statistical measures from aggregate data may only be capable of indication or trends over time. Only consistency provides a mathematical...

I estimate a dynamic optimization model of labor adjustment of establishments based on data that permit: specifying any desired adjustment frequency; estimating the model based on net and on gross employment flows; and allowing for simultaneous hirings and separations. The unit of observation is...

Aggregators are facing increased scrutiny by regulatory authorities, suggesting these sites have considerable market power. On the other extreme, firms are bypassing aggregators, choosing instead to sell directly to consumers. This raises the question as to which party has more market power: the...

We build a modified measure of disaggregation quality (MDQ), based on the disaggregation quality (DQ) measure from Chen, Miao, and Shevlin (2015). Like DQ, MDQ is a parsimonious measure of data disaggregation quality in the annual report that can be constructed through the percentage of...

Judgment aggregation theory generalizes social choice theory by having the aggregation rule bear on judgments of all kinds instead of barely judgments of preference. The paper briefly sums it up, privileging the variant that formalizes judgment by a logical syntax. The theory derives from...

Despite the existence of a near consensus on most of the specifics of common law contract law, there remains a great deal of uncertainty about how doctrines of contractual fairness are to be applied to excuse a party from a contract, and no clear justificatory principle has been found to explain...

Fifty-six percent of the U.S. taxpaying population uses a paid tax preparer, but the effect of these tax preparation services on tax compliance is not well-understood. Although governments conceal the algorithms they use to determine which taxpayers to audit, tax preparation firms with large...

Correctly accounting for the energy and emissions embodied in consumption and trade is essential to effective climate policy design. Robust methods are needed for both policy making and research—for example, the assignment of border carbon adjustments (BCAs) and greenhouse gas emission...
