The race factor in social security

Conclusion A more complete analysis of the race factor in Social Security would expand from here in the following ways. First, projected earnings would be forecast for both races to compute race-specific benefit-tax ratios. Second, more complete family formation data would permit the projection of dependent-less benefit-producing events, not just spouse-less benefitproducing events. Additional computations would be performed for female workers and two-earner families. A satisfactory weight (or a rationale for the present one) would be assigned to survivor benefits. The end-result would be benefit-tax ratios for both races, not just for set-piece workers.     

An Empirical Portfolio Perspective on Option Pricing Anomalies

We empirically study the economic benefits of giving investorsaccess to index options in the standard portfolio problem, analyzingboth expected-utility and nonexpected-utility investors in orderto understand who optimally buys and sells options. Using dataon S&P 500 index options, CRRA investors find it alwaysoptimal to short out-of-the-money puts and at-the-money straddles.The option positions are economically and statistically significantand robust to corrections for transaction costs, margin requirements,and Peso problems. Loss-averse and disappointment-averse investorsalso optimally hold short option positions. Only with highlydistorted probability assessments can we obtain positive portfolioweights for puts (cumulative prospect theory and anticipatedutility) and straddles (anticipated utility).     

Restoring Trust Through the Co-Production of Public Services: A theoretical elaboration

Abstract

Co-production, the involvement of clients in the delivery of public services, is believed to foster trust. However, there is insufficient research on this topic to prove what is at present merely an assumption. This article gives theoretical insights into this relationship. First, it is identified that co-production relates to identification-based trust. Second, the most important theoretical mechanisms are identified that link the two concepts: increasing self-efficacy and the creation of trust networks. A third step is to move towards a more contingent perspective. This involves not only favourable conditions, but also obstructions to trust-building, such as crowding-out motivations and free-riding.     

The Role of Farmer's Behavioral Attitudes and Heterogeneity in Futures Contracts Usage

The relationship between farmers' behavioral attitudes and use of futures contracts is examined, taking into account non-directly observable variables and the heterogeneity of farmers. The relationships are tested on a stratified data sample of 440 farmers. Cluster analysis and covariance structure equation models are used to validate the relationships. Farmers are found not to be homogenous regarding the factors influencing their use of futures. Heterogeneity at the segment level masked important effects at the aggregate level, notably risk attitude. Furthermore, several psychological constructs for farmers related to market orientation, risk exposure, market performance and entrepreneurial behavior play important roles in their use of futures contracts.     

How to predict transfer of training? Investigating the application of the unified model of task-specific motivation

Transfer motivation is an important factor influencing transfer of training. However, earlier research often did not investigate transfer motivation as a multidimensional construct. The unified model of task-specific motivation (UMTM) takes into account that (transfer) motivation is multidimensional by including both affective and cognitive motivational components and their antecedents. Prior research has provided evidence that the UMTM can predict self-reported transfer of training, but is unclear whether it also can predict transfer reported by expert external raters. Moreover, it is unclear whether controlling for prior knowledge matters for the relationship between transfer motivation and transfer of training. This study improves on existing research by accounting for both of these gaps in the literature. Data were collected among 299 participants who filled in a questionnaire about the UMTM components directly after attending a writing training. They also handed in written documents before, and 6 weeks after the training, which were rated on transfer by trainers. Outcomes showed that components of the UMTM positively predict externally reported transfer when prior knowledge was controlled for. The outcomes imply that the UMTM has predictive value for transfer of training and points out which factors influence whether transfer does or does not occur.     

Exploring modern bank penetration: Evidence from early twentieth-century Netherlands

We analyse the estate composition of the richest 30 per cent of people who died in the Netherlands in 1921 to find that households used a broad range of institutions to meet their financial demands. Goods and services were either paid in cash or settled periodically with suppliers. Despite the strong growth of commercial banking in the previous decades, households still made extensive use of peer-to-peer loans, with or without the added security of notarial contracts. Banks only possessed a competitive edge in savings accounts for small surpluses and current accounts, the latter used most frequently by business owners born after 1870. Distance to the nearest bank office did not matter for these people, but wealthy urbanites were more inclined to use banks than their counterparts in the countryside.     

Unravelling the JPMorgan spoofing case using particle physics visualization methods

On 29 September 2020, JPMorgan was ordered to pay a settlement of $920.2 million for spoofing the metals and Treasury futures markets from 2008 to 2016. We examine these cases using a visualization method developed in particle physics (CERN) and the messages that the exchange receives about market activity rather than time-based snapshots. This approach allows to examine multiple indicators related to market manipulation and complement existing research methods, thereby enhancing the identification and understanding of, as well as the motivation for, market manipulation. In the JPMorgan cases, we offer an alternative motivation for spoofing than moving the price.
