Nobel laureate economist Milton Friedman once noted that free immigration cannot coexist with a welfare state. A welfare state with open borders might turn into a haven for poor immigrants, which would place such a fiscal burden on the state that native-born voters would support less-generous benefits or restricted immigration, or both. And yet a welfare state with an aging population might welcome young skilled immigrants.
In The Decline of the Welfare State, Assaf Razin and Efraim Sadka use a political economy framework to analyze the effects of aging populations, migration, and globalization on the deteriorating system of financing welfare state benefits as we know them.
From Malthus to Becker, the economic approach to population growth and its interactions with the surrounding economic environment has undergone a major transformation. Population Economics elucidates the theory behind this shift and the consequences for economic policy.Razin and Sadka systematically examine the microeconomic implications of people's decisions about how many children to have and how to provide for them on population trends and social issues of population policy.
The ongoing process of increased integration of national economies, culminating in the single European market of 1992, still leaves as virtually separate the national fiscal systems. In this book international economists Jacob Frenkel and Assaf Razin join forces with public finance economist Efraim-Sadka to provide a new treatment of international taxation, one that focuses on the interactions between fiscal policies of sovereign nations and the magnitude and directions of international capital and goods flow in an integrated world economy.
