The Role of Income and Immigration Policies in Attracting International Migrants This paper makes two contributions to the literature on the determinants of international migration flows. First, we compile a new dataset on annual bilateral migration flows covering 15 OECD destination countries and 120 sending countries for the period 1980-2006. We also collect data on time-varying immigration p...

Arguably the most important development in recent decades in US factor markets is the decline in the relative wage of the unskilled. By contrast, in Europe it is undoubtedly the rise and persistence of unemployment. Technology has been identified as a key reason for the rising US wage inequality, while labor market rigidities are often cited as a key reason for European unemployment. This paper...

The paper studies the effects of cross-country differences in human capital formation on income distributions. Our overlapping generations economy has the following features: (1) consumers are heterogenous with respect to ability and parental human capital; (2) intergenerational transfers take place via parental education and, public investments in education Þnanced by taxes (possibly, with a l...

Although the technology of fuel injection in motorcycles has reached ports and direct injection, with carburetors are still used. In this research, carburetor was modified by adding a swirling vane. This study is intended to provide an explanation regarding engine performance which includes torque, power, mileage, emissions, oil temperature. The begins review shape flow characteristics vane bas...

This paper studies how changes in oil supply expectations affect the price and macroeconomy. Using a novel identification design, exploiting institutional features of OPEC high-frequency data, I identify an news shock. These shocks have statistically economically significant effects. Negative leads to immediate increase prices, gradual fall production, inventories. has consequences for US econo...

If the Mortensen and Pissarides model with efficient bargaining is calibrated to replicate the fluctuations of unemployment over the business cycle, it implies a far too strong rise of the unemployment rate when unemployment benefits rise. This paper explores an alternative, right-to-manage bargaining scheme. This also generates the right degree of fluctuations of unemployment but at the same t...

Multiresolution wavelet analysis is a natural way to decompose economic time series into components of various frequencies: long-run trend, business-cycle component, and high frequency noise. This paper illustrates the method on real GNP and inflation. The business-cycle component of the wavelet-filtered series closely resembles the series filtered by the approximate bandpass filter (Baxter and...

We provide two ways to reconcile small values of the intertemporal elasticity of substitution (IES) that range between 0.35 and 0.5 with empirical evidence that the IES is large. We do this reconciliation using a model in which all agents have identical preferences and the same access to asset markets. We also conduct an encompassing test, which indicates that specifications of the model with s...

Durable goods are an important component of the business cycle. Equilibrium models of durable goods markets are made difficult by the lumpy nature of individual purchases. We show that a straight forward approximation of the distribution of durable goods holdings gives rise to a tractable equilibrium model. We analyze the case of competition as well as that of a monopoly producer. J.E.L. Classi...
