Abstract Thermochemical exhaust energy recovery in a modern gasoline direct injection engine is investigated using ethanol-gasoline blend (E25) and gasoline, as base fuel. The primary objectives of this research are focused on reducing carbonaceous emissions well improving thermal efficiency fuel economy combustion engines. These consistent with the global commitment to lessen carbon meet envir...

We incorporate a wage-bargaining structure in a dynamic general equilibrium model and show how this feature changes shortand long-run properties of equilibria compared with a perfectly competitive setting. We discuss how employment, capital and income shares respond to wage-setting shocks and show that adjustment dynamics depend decisively on the magnitude of the elasticity of substitution betw...

This paper challenges the current belief that income inequality has a negative relationship with economic growth. It uses an improved data set on income inequality which not only reduces measurement error, but also allows estimation via a panel technique. Panel estimation makes it possible to control for time-invariant country-specific effects, therefore eliminating a potential source of omitte...

I analyze an economy in which firms can undertake both laborand capital-augmenting technological improvements. In the long run, the economy resembles the standard growth model with purely labor-augmenting technical change, and the share of labor in GDP is constant. Along the transition path, however, there is capital-augmenting technical change and factor shares change. Tax policy and changes i...

This paper revisits the important ideas proposed by Atkinson and Stiglitz’s seminal 1969 paper on technological change. After linking these ideas to the induced innovation literature of the 1960s and the more recent directed technological change literature, it explains how these three complementary but different approaches are useful in the study of a range of current research areas– though the...

In this paper we study the evolution of the labor share in the OECD since 1970. We show it is essentially related to the capital-output ratio; that this relationship is shifted by factors like the price of imported materials or the skill mix; and that discrepancies between the marginal product of labor and the real wage (due to, e.g., product market power, union bargaining, and labor adjustment...

This paper examines how domestic, foreign, private and public investments affect incomeinequality through financial intermediary dynamics. With the exception of financial allocation efficiency, financial channels of depth and activity are good for the poor as they diminish estimated household income-inequality. Financial size does not have a significant incomeredistributive effect. Financial ef...

This paper explores the ability of some popular income distributions to model observed skewness and kurtosis. We present the generalized beta type 1 (GB1) and type 2 (GB2) distributions’ skewnesskurtosis spaces and clarify and expand on previously known results on other distributions’ skewnesskurtosis spaces. Data from the Luxembourg Income Study are used to estimate sample moments and explore ...

Comparing a process of laborand capital-augmenting technical change directed by capitalists’ maximization of profits with a counterfactual in which decentralized innovation decisions are governed by noncapitalist property relations, I claim that if the two economies start from the same technology and capital stock there’s a date T such that after T per-capita consumption is always strictly grea...
