Which Inequality? The Inequality of Endowments Versus the Inequality of Rewards

Society often allocates valuable resources - such as prestigious positions, salaries, or marriage partners - via tournament-like institutions. In such situations, inequality affects incentives to compete and hence has a direct effect on equilibrium choices and hence material outcomes. We introduce a new distinction between inequality in initial endowments (e.g. ability, inherited wealth) and inequality of what one can obtain as rewards (e.g. prestigious positions, money). We show that these two types of inequality have opposing effects on equilibrium behavior and wellbeing. Greater inequality of rewards tends to hurt most people — both the middle class and the poor, — who are forced into greater effort. In contrast, greater inequality of endowments tends to benefit the middle class. Thus, which type of inequality is considered hugely affects the correctness of our intuitions about the implications of inequality.

The Design and efficiency of loyalty rewards

The goal of this paper is to reexamine the optimal design and efficiency of loyalty rewards in markets for final consumption goods. While the literature has emphasized the role of loyalty rewards as endogenous switching costs (which distort the efficient allocation of consumers), in this paper I analyze the ability of alternative designs to foster consumer participation and increase total surplus. First, the efficiency of loyalty rewards depend on their specific design. A commitment to the price of repeat purchases can involve substantial efficiency gains by reducing price-cost margins. However, discount policies imply higher future regular prices and are likely to reduce total surplus. Second, firms may prefer to set up inefficient rewards (discounts), especially in those circumstances where a commitment to the price of repeat purchases triggers Coasian dynamics.

Market rewards to patterns on increasing earnings: do cash flow patterns, accruals manipulation and real activities manipulation matter?

This study explores whether firms have differential price-earnings multiples associated with their means of achieving a sequential pattern of increasing positive earnings. Our main findings show that market participants assign higher price-earnings multiples to firms when their pattern of increasing earnings is supported by the same pattern of increasing cash flows. Market participants assign lower price-earnings multiples to firms suspect of having engaged in accrual-based earnings management, sales manipulation, and overproduction to achieve the earnings pattern. We find, however, that market participants do not penalize firms suspect of having achieved the earnings pattern through the opportunistic reduction of discretionary expenses.

Motivating Students to Learn English: Intrinsic and Extrinsic Strategies to Meet the Needs of First Time Learners

Motivation is the key to learning. The present study is about the relationship between intrinsic and extrinsic motivation as they affect learning with regard to students who are learning EFL for the first time. Cape Verdean seventh grade students learning English for the first time are generally very enthusiastic about the language before they start learning it in the high school. However, that enthusiasm seems not to be maintained throughout the school year and oftentimes teachers hear them complain about the difficulties of mastering aspects of the language. It seems that for some reason their motivation is undermined. Why does that happen? Is it the students’ fault or the teacher’s? If it the teacher’s fault, which motivation strategies work best to cope with this problem: intrinsic or extrinsic? With this in mind I asked the question: What is the relationship between students’ needs, interests, goals and expectations to learn English as a foreign language and teachers’ roles as facilitators and motivators? There are many studies that have been carried out in the field of motivation, and up to now, there seems to be no consensus of which is the best. For the purposes of this paper, three main theories will be discussed that have prevailed in the field of motivational psychology: the behavioural, the cognitive and the humanistic theories. Within these theories sub-theories are discussed and their relationship is explained with intrinsic and extrinsic motivation regarding Cape Verdean students learning English for the first time.

Analysis of the near-intrinsic and extrinsic photocapacitance due to the EL2 level in boron implanted GaAs

A detailed analysis of the photocapacitance signal at the near‐band and extrinsic energetic ranges in Schottky barriers obtained on horizontal Bridgman GaAs wafers, which were implanted with boron at different doses and annealed at several temperatures, has been carried out by using the optical isothermal transient spectroscopy, OITS. The optical cross sections have been determined as well as the quenching efficiency of the EL2 level which has been found to be independent of the annealing temperature. Moreover, the quenching relaxation presents two significant features: (i) a strong increase of the quenching efficiency from 1.35 eV on and (ii) a diminution of the quenching transient amplitude in relation with that shown by the fundamental EL2 level. In order to explain this behavior, different cases are discussed assuming the presence of several energy levels, the existence of an optical recuperation, or the association of the EL2 trap with two levels located, respectively, at Ev+0.45 eV and Ec−0.75 eV. The theoretical simulation, taking into account these two last cases, is in agreement with the experimental photocapacitance data at low temperature, as well as at room temperature where the EL2 filling phototransient shows an anomalous behavior. Moreover, unlike the previous data reported for the EL2 electron optical cross section, the values found using our experimental technique are in agreement with the behavior deduced from the theoretical calculation. The utilization of the OITS method has also allowed the determination of another level, whose faster optical contribution is often added to that of the EL2 level when the DLOS or standard photocapacitance is used.

The rewards of cooperation: The effects of membership in European regulatory networks

Networks famously epitomize the shift from 'government' to 'governance' as governing structures for exercising control and coordination besides hierarchies and markets. Their distinctive features are their horizontality, the interdependence among member actors and an interactive decision-making style. Networks are expected to increase the problem-solving capacity of political systems in a context of growing social complexity, where political authority is increasingly fragmented across territorial and functional levels. However, very little attention has been given so far to another crucial implication of network governance - that is, the effects of networks on their members. To explore this important question, this article examines the effects of membership in European regulatory networks on two crucial attributes of member agencies, which are in charge of regulating finance, energy, telecommunications and competition: organisational growth and their regulatory powers. Panel analysis applied to data on 118 agencies during a ten-year period and semi-structured interviews provide mixed support regarding the expectation of organisational growth while strongly confirming the positive effect of networks on the increase of the regulatory powers attributed to member agencies.

Palliative portal vein stent placement in malignant and symptomatic extrinsic portal vein stenosis or occlusion.

This article evaluates the results of portal vein (PV) stent placement in patients with malignant extrinsic lesions stenosing or obstructing the PV and causing symptomatic PV hypertension (PVHT). Fourteen patients with bile duct cancer (n = 7), pancreatic adenocarcinoma (n = 4), or another cancer (n = 3) underwent percutaneous transhepatic portal venous stent placement because of gastroesophageal or jejunal varices (n = 9), ascites (n = 7), and/or thrombocytopenia (n = 2). Concurrent tumoral obstruction of the main bile duct was treated via the transhepatic route in the same session in four patients. Changes in portal venous pressure, complications, stent patency, and survival were evaluated. Mean +/- standard deviation (SD) gradient of portal venous pressure decreased significantly immediately after stent placement from 11.2 mmHg +/- 4.6 to 1.1 mmHg +/- 1.0 (P < 0.00001). Three patients had minor complications, and one developed a liver abscess. During a mean +/- SD follow-up of 134.4 +/- 123.3 days, portal stents remained patent in 11 patients (78.6%); stent occlusion occurred in 3 patients, 2 of whom had undergone previous major hepatectomy. After stent placement, PVHT symptoms were relieved in four (57.1%) of seven patients who died (mean survival, 97 +/- 71.2 days), and relieved in six (85.7%) of seven patients still alive at the end of follow-up (mean follow-up, 171.7 +/- 153.5 days). Stent placement in the PV is feasible and relatively safe. It helped to relieve PVHT symptoms in a single session.

Acute life-threatening extrinsic allergic alveolitis in a paint controller.

BACKGROUND: Occupational diisocyanate-induced extrinsic allergic alveolitis (EAA) is a rare and probably underestimated diagnosis. Two acute occupational EAA cases have been described in this context, but neither of them concerned hexamethylene diisocyanate (HDI) exposure. AIMS: To investigate the cause of a life-threatening EAA arising at work in a healthy 30-year-old female paint quality controller. METHODS: Occupational medical assessment, workplace evaluation, airborne and biological monitoring and immunodermatological tests. RESULTS: Diagnosis of EAA relied on congruent clinical and radiological information, confirmed occupational HDI exposure and positive IgG antibodies and patch tests. The patient worked in a small laboratory for 7 years, only occasionally using HDI-containing hardeners. While working with HDI for 6 h, she developed breathlessness, rapidly progressing to severe respiratory failure. Workplace HDI airborne exposure values ranged from undetectable levels to 4.25 p.p.b. Biological monitoring of urinary hexamethylene diamine in co-workers ranged from <1.0 to 15.4 μg/g creatinine. Patch tests 8 months later showed delayed skin reaction to HDI at 48 h. Subsequent skin biopsy showed spongiotic dermatitis with infiltration of CD4(+) and CD8(+) T cells. CONCLUSIONS: We believe this is the first reported case of acute life-threatening EAA following exposure to HDI. Low concentrations of airborne HDI and relatively high urinary hexamethylene diamine suggest significant skin absorption of HDI could have significantly contributed to the development of this acute occupational EAA.

Monipuolinen tietotyö tilitoimistossa - kiinnostava vaihtoehto valmistuvalle?

Tutkimuksen tarkoitus on tuottaa ajantasaista tietoutta siitä, millainen käsitys laskenta-alan tradenomi- ja maisteriopiskelijoilla on tämän päivän tilitoimistotyöstä ja koetaanko tilitoimisto kiinnostavana työpaikkana. Asiaa tarkasteltiin tietotyön monipuolisuuden ja motivaation näkökulmasta. Tutkimuksen empiirinen osuus toteutettiin nettikyselynä, joka kohdistettiin viimeisen vuoden taloushallinnon tai laskentatoimen pääainetta Suomessa opiskeleville tradenomi- ja maisteriopiskelijoille. Vastauksia saatiin 182, joista 162 oli tradenomi- ja 20 kauppatieteiden maisteriopiskelijoilta. Tutkimus toteutettiin kvantitatiivisena. Vastaajista 55 prosenttia pititilitoimistoa kiinnostavana ja 25 prosenttia melko kiinnostavana työpaikkana. Tulokset osoittavat, että tilitoimistotyö on kiinnostava vaihtoehto henkilöille, jotka kokevat työn itseään sisäisesti motivoivaksi. Sisäistä motivaatiota voidaan parantaa ulkoiseen motivaatioon vaikuttavia, kuten rahallisia ja sosiaalisia palkkioita, lisäämällä. Myös asiakaslähtöiset työtehtävät ja verkostomainen toimintatapa vaikuttavat sisäiseen motivaatioon. Työntekijän vaikutusmahdollisuudet omaan työhönsä lisäävät puolestaan ulkoista motivaatiota. Tieto- ja viestintätekniikan monipuolinen hyödyntäminen selittää ulkoisesta motivaatiosta pienen osan. Tietotyön ulottuvuuksista ainoastaan koulutus- ja kehittämismahdollisuudet eivätvaikuta motivaatioon eivätkä tilitoimiston kiinnostavuuteen työpaikkana. Tulokset osoittavat tilitoimistotyön olevan tulevien tietotyöntekijöiden näkemyksen mukaan monipuolista tietotyötä. Tilitoimistotyössä hyödynnetääntieto- ja viestintätekniikkaa monipuolisesti, ja se sisältää omaa suunnittelua vaativia työtehtäviä. Työ vaatii tekijältään korkeaa ja laaja-alaista osaamista sekä jatkuvaa itsensä kehittämistä. Tilitoimistot toimivat sekä sisäisissä että ulkoisissa verkostoissa, joten työntekijät tarvitsevat myös sosiaalisia taitoja.Tilitoimistot tarjoavat työntekijöille melko hyvät vaikutusmahdollisuudet omaantyöhönsä. Tilitoimistotyön arvioitiin tarjoavan muuta tietotyötä paremmat koulutus- ja itsensä kehittämismahdollisuudet. Huolimatta monipuolisuudesta tietotyönnäkökulmasta, tilitoimistotyötä pidettiin yleensä liian säännöllisenä rutiinityönä.

Rewards for Motivating Employees

When considering ways to motivate employees, one must keep in mind that each individual is different and therefore everyone is motivated in different way. Employees can have quite different motivators, for example, more money, more recognition, flexible working hours, promotions, opportunities for learning, or discounts for employee and his/her family. Therefore, when attempting to help motivate people, it is important to discover what the individual motivation factors are for each one personally. Another key factor is the variation over time. Nobody experiences a constant set of needs over time, it will change slowly. One of the most fundamental concerns of reward management is how it can help to motivate people so that they achieve their full potential. The development of a performance culture is a typical aim of reward strategy. It is therefore necessary to understand the factors that motivate people and how, in the light of these factors, rewarding process and practices that will enhance motivation, commitment, job engagement and positive discretionary behavior, can be developed. The purpose of this research is to examine more in detail of the total reward systems which are used in two public sectors and their cultural differences and/or similarities. The study is focused on two different public sectors; Vantaa City Authority (Finland) and Hertfordshire County Authority (the United Kingdom). The research questions are: How do public sector employers attempt to reward their employees with a total reward system? • What are the different ways to motivate employees? • What is the reward system in the public sector based on? • What characteristics are included in the total reward system? • How does the culture affect the ways of motivation and rewarding? The benefits of a total reward approach are, for example, the greater impact which means that the combined effect of the different types of rewards will make a deeper and longer-lasting impact on the motivation and commitment of people. It also enhances the employment relationship, meaning that the employment relationship created by a total rewards approach makes the maximum use of relational as well as transactional rewards and will therefore appeal more to individuals. The research findings point out that in Finland rewards are based on just for the employees, recognition of individuals is high, in several cases they reward teams, and organisation climate is important issue for them. In the United Kingdom, the reward system is based on rewarding employees and their families, employer offer several discounts for employees and families, and flexible working hours are favourable.

The effects of athletic scholarships on motivation in sport

The presence of rewards has been found to undermine intrinsic motivation (Deci & Ryan, 1999). This conclusion is primarily based on research conducted in non-sporting environments. The purpose of this study was to examine perceived motivational changes resulting from the hypothetical manipulation of a reward (i.e., athletic scholarships). Differences in "present" motivation between scholarship and non-scholarship athletes were also assessed. Gender, life roles, and sport experience were also examined in relation to scholarship status. Basketball players from four Ontario (n = 70) and seven U.S. Division I universities (n = 46) were examined. All athletes completed a set of demographic questions, as well as questions from the Sport Motivation Scale (SMS; Pelletier, Fortier, Vallerand, Tuson, Briere, & Blais, 1995) which assessed their "present" motivation. Athletes also completed the SMS to evaluate their "perceived future" motivation based on a hypothetical manipulation of the scholarship status. For Ontario non-scholarship athletes, extrinsic regulation (an extrinsic motive) increased with the introduction of a scholarship and the intrinsic motive to experience stimulation decreased. For U.S. scholarship athletes, the intrinsic motive to accomplish things decreased when scholarships were removed. When the two scholarship status groups were compared across "present" levels of motivation, U.S. scholarship males reported significantly higher levels of introjected regulation compared to Ontario non-scholarship males. Ontario non-scholarship females reported significantly higher levels of introjected regulation compared to U.S. scholarship females. U.S. scholarship athletes reported significantly higher levels of external regulation compared to Ontario non-scholarship athletes. Results offer partial support for self-determination theory. Implications for future research are discussed.

Regulatory History Material as an Extrinsic Aid to Interpretation: An Empirical Study on the Use of RIAS by the Federal Court of Canada

Since 1986, the Canadian Public Administration is required to analyze the socio-economic impact of new regulatory requirements or regulatory changes. To report on its analysis, a Regulatory Impact Analysis Statement (RIAS) is produced and published in the Canada Gazette with the proposed regulation to which it pertains for notice to, and comments by, interested parties. After the allocated time for comments has elapsed, the regulation is adopted with a final version of the RIAS. Both documents are again published in the Canada Gazette. As a result, the RIAS acquires the status of an official public document of the Government of Canada and its content can be argued in courts as an extrinsic aid to the interpretation of a regulation. In this paper, an analysis of empirical findings on the uses of this interpretative tool by the Federal Court of Canada is made. A sample of decisions classified as unorthodox show that judges are making determinations on the basis of two distinct sets of arguments built from the information found in a RIAS and which the author calls “technocratic” and “democratic”. The author argues that these uses raise the general question of “What makes law possible in our contemporary legal systems”? for they underline enduring legal problems pertaining to the knowledge and the acceptance of the law by the governed. She concludes that this new interpretive trend of making technocratic and democratic uses of a RIAS in case law should be monitored closely as it may signal a greater change than foreseen, and perhaps an unwanted one, regarding the relationship between the government and the judiciary.

Thermal characterization of intrinsic and extrinsic InP using photoacoustic technique

An open photoacoustic cell operating in the low range of chopping frequency has been employed to evaluate the thermal diffusivity values of intrinsic InP and InP doped with S, Sn and Fe. The experimental set-up is calibrated by the evaluation of thermal diffusivity value of pure Si and GaAs. The present investigation shows that doped samples show a reduced value for thermal diffusivity compared to intrinsic sample. From the analysis of data it is also seen that nature of dopant clearly influences the thermal diffusivity value of semiconductors. The results are explained in terms of phonon assisted heat transfer mechanism in semiconductors
