Introducing shift operators on time scales we construct the integro-dynamic equation corresponding to the convolution type Volterra differential and difference equations in particular cases T = R and T = Z. Extending the scope of time scale variant of Gronwall’s inequality we determine function bounds for the solutions of the integro dynamic equation.

In this paper, we deal with the complex relationship connecting inequality to innovation, and the ways through which public investment, in particular public participation to R&D initiatives, can affect it. We first stress that various different equilibria may exist in the inequality-innovation space. The positive relation that part of the economic theory often assumes to exist between (initiall...

If two identical emitters are coupled to a common reservoir, entanglement can be generated during the decay process. When using Bell's inequality to examine the non-locality, however, it is possible that the bound cannot be violated in some cases. Here, we propose to use the steering inequality to examine the non-locality induced by a common reservoir. Compared with the Bell inequality, we find...

In this paper we revisit the relationship between democracy, redistribution, and inequality. We first explain the theoretical reasons why democracy is expected to increase redistribution and reduce inequality, and why this expectation may fail to be realized when democracy is captured by the richer segments of the population; when it caters to the preferences of the middle class; or when it ope...

This paper seeks to analyze the dynamic behavior of prime-age male workers’ earnings inequality in the formal labor market of the State of São Paulo in the years 1990-1998. The aim is to fit an econometric model of unobserved earnings components into the empirical earnings variance-covariance structure in order to evaluate the relative magnitude of individual characteristics and earnings instab...

Economic segregation increased in the United States between 1970 and 1990. Three hypotheses suggest that this would affect low-income children’s educational attainment. The political economy of school funding and predicts that economically segregated school districts reduce the educational attainment of low-income children. Two other hypotheses emphasize the effect of inequality within neighbor...

This study attempts to convey an accurate and dynamic account of educational inequality in China during the last decade. The study finds that there is clear evidence of rapid expansion of education, and younger students all over China are benefiting from the expansion. One of the most notable achievements is the virtual elimination of gender bias against girls in educational attainment. However...

BACKGROUND Symptomatic leg length inequality accounts for 8.7% of total hip replacement related claims made against the UK National Health Service Litigation authority. It has not been established whether symptomatic leg length inequality patients following total hip replacement have abnormal hip kinetics during gait. METHODS Hip kinetics in 15 unilateral total hip replacement patients with s...

Proving that a function satisfies the quadrangle inequality is a powerful and elegant way to show that a dynamic programming algorithm to compute that function can be sped up by a factor of the input size. In this paper we consider two problems that do no fit in the usual general cases of functions that satisfy the quadrangle inequality but for which the proof of the quadrangle inequality still...

This paper discusses the implications of the decomposition property of the Theil index in sequences of nested and hierarchic grouping structures, formalizing general results applicable to a generic sequence of grouping structures. A specific application to data on wages and employment by industrial classification to measure the evolution of wage inequality through time will be explored, analyzi...
