Audit probability versus effectiveness: The Beckerian approach revisited

The Beckerian approach to tax compliance examines how a tax authority can maximize social welfare by trading-off audit probability against the fine rate on undeclared tax. This paper offers an alternative examination of the privately optimal behavior of a tax authority tasked by government to maximize expected revenue. The tax authority is able to trade-off audit probability against audit effectiveness, but takes the fine rate as fixed in the short run. I find that the tax authority's privately optimal audit strategy does not maximize vol- untary compliance, and that voluntary compliance is non-monotonic as a function of the tax authority's budget. Last, the tax authority's privately optimal effective fine rate on undeclared tax does not exceed two at interior optima

Self-employment, wage employment and informality in a developing economy

This article has been made available through the Brunel Open Access Publishing Fund.We construct a simple model incorporating various urban labour market phenomena obtaining in developing economies, and we give a diagrammatic formulation of the market equilibrium. Our initial formulation assumes an integrated labour market and allows for entrepreneurship, self-employment, and wage employment. We then introduce labour market segmentation. In equilibrium voluntary and involuntary self-employment, formal and informal wage employment, and formal and informal entrepreneurship may all coexist. We illustrate the model by an example calibrated on Latin American data, examining individual labour market transitions and implications of education/training and labour market policies

Ring Expansion Of Alkylidenecarbenes Derived From Lactams, Lactones, And Thiolactones Into Strained Heterocyclic Alkynes: A Theoretical Study

Strained cycloalkynes are of considerable interest to theoreticians and experimentalists, and possess much synthetic value as well. Herein, a series of cyclic alkylidenecarbenes—formally obtained by replacing the carbonyl oxygen of four-, five-, and six-membered lactams, lactones, and thiolactones with a divalent carbon—were modeled at the CCSD(T)/cc-pVTZ//B3LYP/6-311+G** and CCSD(T)/cc-pVTZ//CCSD/6-311+G** levels of theory. The singlet carbenes were found to be more stable than the triplets. The strained heterocyclic alkynes formed by ring expansion of these singlet carbenes were also modeled. Interestingly, the C≡C bonds in the five-membered heterocycles, obtained from the rearrangement of β-lactam- and β-lactone-derived alkylidenecarbenes, displayed lengths intermediate between formal double and triple bonds. Furthermore, 2-(1-azacyclobutylidene)carbene was found to be nearly isoenergetic with its ring-expanded isomer, and 1-oxacyclopent-2-yne was notably higher in energy than its precursor carbene. In all other cases, the cycloalkynes were lower in energy than the corresponding carbenes. The transition states for ring-expansion were always lower for the 1,2-carbon shifts than for 1,2-nitrogen or oxygen shifts, but higher than for the 1,2-sulfur shifts. These predictions should be verifiable using carbenes bearing appropriate isotopic labels. Computed vibrational spectra for the carbenes, and their ring-expanded isomers, are presented and could be of value to matrix isolation experiments

A Complex Stereochemical Relay Approach To The Antimalarial Alkaloid Ocimicide A1. Evidence For A Structural Revision

Ocimicide A1 (1) and the semisynthetic derivative ocimicide A2 (2) are highly potent antimalarial agents efficacious against chloroquine-sensitive and -resistant Plasmodium falciparum strains with IC50 values in the nanomolar and picomolar range, respectively. Members of this family have demonstrated radical cure in rhesus monkeys, without detectable toxicity, but their structure–function relationships and mechanism of action are unknown. Herein we describe a twelve-step synthesis of an advanced N-acylated pentacyclic precursor to the proposed structure of 1 (11% overall yield). Instability and poor P. falciparum growth inhibition of the corresponding free donor–acceptor cyclopropylamine, and large discrepancies between reported and both experimental and DFT-calculated 13C chemical shifts and coupling constants, suggest that substantial revision of the proposed structures may be necessary

Reform of the United Nations Security Council: equity and efficiency

The United Nations Security Council (UNSC) is critical to global peace and security, yet more than 20 years of negotiations over its reform have proved fruitless. We use recent advances in the theory of a priori voting power to present a formal quantitative appraisal of the implications for democratic equity and efficiency of the “structural reforms” contained within 11 current reform proposals, as well as the separate effect of expansion of the UNSC membership. Only one reform proposal–a weakening of the veto power for Permanent Members by requiring two negative votes for a veto to be effective— robustly dominates the status quo against our measures of equity and efficiency. Several proposed structural reforms may actually worsen the issues they ostensibly claim to resolve

Bribery, Hold-Up and Bureaucratic Structure

We analyze the provision of infrastructure by a foreign investor when the domestic bureaucracy is corrupt, but puts some weight on domestic welfare. The investor may pay a bribe in return for a higher provisional contract price. After the investment has been sunk, the bureaucracy may hold up the investor, using the threat of expropriation to demand a lower final price or another bribe. Depending on the level of care for domestic welfare, greater bureaucratic centralization may increase or decrease domestic welfare. Because of the threat of hold-up, bribery may result in greater domestic welfare than the honest benchmark does

Synthesis And Characterization Of (pyNO−)2GaCl: A Redox-Active Gallium Complex

We report the synthesis of a gallium complex incorporating redox-active pyridyl nitroxide ligands. The (pyNO−)2GaCl complex was prepared in 85% yield via a salt metathesis route and was characterized by 1H and 13C NMR spectroscopies, X-ray diffraction, and theory. UV–Vis absorption spectroscopy and electrochemistry were used to access the optical and electrochemical properties of the complex, respectively. Our discussion focuses primarily on a comparison of the gallium complex to the corresponding aluminum derivative and shows that although the complexes are very similar, small differences in the electronic structure of the complexes can be correlated to the identity of the metal

Self-reporting and market structure

Many regulators utilize self-reporting, that is, wrongdoers reporting their own crimes to the authority, to enforce regulations in a variety of market contexts. This paper studies the effectiveness of self-reporting within the context of an oligopoly. We identify two important consequences of implementing self-reporting (relative to no-reporting) for a welfare-maximizing regulator. First, if the regulator can control only the audit probability and fine, then whether compliance rises or falls upon implementing self-reporting depends on the level of competition. Second, if the regulator can also control the market size, then the welfare-maximizing policy entails self-reporting but with more competition and lower compliance than under no-reporting

Economic transition and happiness and life satisfaction in Algeria, Egypt and Morocco

The present research aims at examining the interaction between transition from centrally planned economies to market based economies and its subsequent effects on populations’ happiness and life satisfaction in Algeria, Egypt and Morocco. It also aims at advising policy makers on how economic policies may affect population’s subjective well-being. It is widely accepted that economic reforms affect individuals’ lives. In contrast, the populations’ values, attitudes and perceptions may also play a major role in the success of these reforms. The first study examines the determinants of happiness and life satisfaction by gender in Algeria and their attitudes and perceptions towards economic policies’ reforms. The survey reports that the female population in Algeria is happier and more satisfied with life than its male counterpart. It has been found that healthier individuals and those in the medium level of income are most likely to be happier and satisfied with their lives. Also, happiness is inversely “U-shaped” in age for the female population contradicting previous studies. Although, both genders believe that rapid market reforms do not have a negative impact on national stability, and are confident with the major companies, privatisation is found to be most likely having a negative effect on the life satisfaction among the male population. The second study examines the changes in the levels of life satisfaction in Egypt and Morocco over the first decade of the present century. It has been found that Egyptian women’ satisfaction with life is “U-shaped” in age, whereas in income that applies only to those at the medium, upper-medium and high levels of income. By contrast, Egyptian men are satisfied at all income levels. In Morocco, unemployed men and women are found to be satisfied with their lives in the beginning of the decade contradicting previous findings. While in the late 2000s, among the employed populations, females and males at the medium and the upper medium levels of income are satisfied, along with the lower level for women and the higher level for men. The third study examines the effect of relative income on individuals’ self-reported life satisfaction, assuming that the individual’s subjective judgement of his or her life satisfaction depends on both absolute and relative incomes. Absolute refers to the individual’s income, relative is the income of others around him or her called a reference group. The findings are that Algerians and Moroccans feel ambitious when self-reporting their levels of life satisfaction and referring their income to others’ income, but Egyptians feel jealous.EThOS - Electronic Theses Online ServiceGBUnited Kingdo
