Spouses’ earnings association and inequality: A non-linear perspective

We analyze the association between spouses’ earnings taking account of non-linearities along both spouses’ distribution of earnings. We also document the non-linearity of the relationships between earnings and labor force participation, earnings and couple formation, and earnings and number of children. Using simulations, we then analyze how changes in spouses’ rank-dependence structure, labor force participation and couple formation contribute to the upsurge in inequality in the U.S between 1967 and 2018. We find that an increased tendency towards positive sorting contributed substantially to the rise in inequality only among dual-earner couples, while it contributed little to overall inequality across households. Temporal and distributional heterogeneity are important, as earnings association had a more substantial role in the bottom of the earnings distribution and in recent years. The decline in couple formation contributed substantially to the rise in inequality, while the increase in female labor force participation and the fertility decline had equalizing effects.

     

Privatising social housing in Taiwan

This article first reviews how the concept of privatisation has been referred to in the current restructuring of the social housing system, especially in the case of the UK. The term 'privatisation' is then examined in greater detail and its wider meaning is discussed. By using the network approach, privatisation in relation to housing can be understood in terms of the changing combinations of agents involved in providing social housing, which gives rise to the commodified impact on the distribution of social housing. By using the privatisation process of social housing in Taiwan as an example, three distinct combinations in terms of providing social housing are identified. With an increasing number of social housing units being provided by the marketised social housing model where private agents control the process of providing social housing, along with more market rules being involved in the provision and the partial removal of means tests in relation to the distribution of social housing, the privatisation of social housing development in Taiwan is having a major impact on equity.     

Status quo bias in decision making

Most real decisions, unlike those of economics texts, have a status quo alternative—that is, doing nothing or maintaining one's current or previous decision. A series of decision-making experiments shows that individuals disproportionately stick with the status quo. Data on the selections of health plans and retirement programs by faculty members reveal that the status quo bias is substantial in important real decisions. Economics, psychology, and decision theory provide possible explanations for this bias. Applications are discussed ranging from marketing techniques, to industrial organization, to the advance of science.     

Eating Its Own: The Whistleblower's Organization in Vendetta Mode

This paper reports on Australia's largest whistleblower study. Specifically it focuses on the experiences of whistleblowers in the Queensland public sector during the Goss Labor government's first term. Rather than being affirmed as good citizen-workers when they took disclosures of wrongdoing to their supervisors within the units in which they worked, the whistleblowers encountered obstruction and vilification. Their experiences offer a rare check-up on the state of workplace dissent.     

Use of Single-System Research to Evaluate the Effectiveness of Cognitive-Behavioural Treatment of Schizophrenia

E-mail: Bbradsha{at}che.umn.edu Summary Practitioner research that utilizes single-system designs andreplication studies has been promoted as a means to developpsychosocial interventions of demonstrated effectiveness. Atthe same time, there has been relatively little practitionerpublication of single-system studies. The purpose of this studywas to evaluate the effectiveness of cognitive-behavioural interventionsin the treatment of schizophrenia. The study used a single-systemmultiple baseline design across seven subjects to evaluate changein clinical outcomes. The AB design included a (A) baselinephase and (B) cognitive-behavioural intervention phase. Standardizedmeasures of psychosocial functioning, severity of symptoms andattainment of treatment goals were used to assess change overthe course of three years treatment. A pre-test/post-test designwas used to measure achievement of treatment goals. All sevenclients made statistically significant improvement in psychosocialfunctioning when the baseline mean was compared to the interventionmean. The average effect size for the seven cases was 2.96.All seven clients made a statistically significant reductionin severity of psychiatric symptoms when the baseline mean wascompared to the intervention mean. The average effect size forthe seven cases was -2.19. All seven clients exceeded the expectedlevel of attainment of treatment goals. The pre-test averagegoal attainment score for the seven cases was 20.65 (sd = .55).The average post-test score was 71 (sd = 8). Directions forfuture research and the applicability of single-system designsfor the practitioner researcher evaluation of mental healthpractice are discussed.     

Condorcet's paradox and the likelihood of its occurrence: different perspectives on balanced preferences*

Many studies have considered the probability that a pairwise majority rule (PMR) winner exists for three candidate elections. The absence of a PMR winner indicates an occurrence of Condorcet's Paradox for three candidate elections. This paper summarizes work that has been done in this area with the assumptions of: Impartial Culture, Impartial Anonymous Culture, Maximal Culture, Dual Culture and Uniform Culture. Results are included for the likelihood that there is a strong winner by PMR, a weak winner by PMR, and the probability that a specific candidate is among the winners by PMR. Closed form representations are developed for some of these probabilities for Impartial Anonymous Culture and for Maximal Culture. Consistent results are obtained for all cultures. In particular, very different behaviors are observed for odd and even numbers of voters. The limiting probabilities as the number of voters increases are reached very quickly for odd numbers of voters, and quite slowly for even numbers of voters. The greatest likelihood of observing Condorcet's Paradox typically occurs for small numbers of voters. Results suggest that while examples of Condorcet's Paradox are observed, one should not expect to observe them with great frequency in three candidate elections.
