A quality versus quantity theory of fertility is proposed that predicts that more able parents chose to produce fewer children because they wish to invest more in their children's education. Using Mincer residuals to measure the unobserved ability of parents, data for Israel are used to show...

We create a longitudinal data set by matching immigrants in Israel’s censuses for 1983 and 1995. These panel data reject the Immigrant Assimilation Hypothesis (IAH), which predicts that immigrants with shorter durations in 1983 should have experienced faster earnings growth between 1983 and...

Using quarterly data from 1970-1987 we estimate a simple econometric model in which inflation and the money supply are jointly determined and in which expectations of inflation are rational, or forward-looking. The model is estimated using the recently developed `cointegration' principle in...

According to Wicksell's Classical Dichotomy the money rate of interest depends on the natural rate of interest, but the latter does not depend on the former. If this Classical Dichotomy is false monetary policy may induce hysteresis because the natural rate of interest would depend upon the...

The literature on regional growth convergence and economic disparities has tended to confound four interwoven measurement phenomena. i) mean reversion (so-called beta convergence) where richer regions move towards the average from above and poorer regions from below. ii) diminishing inequality...
