The articles compiled in this volume are studies by Jacob (Kobi) Metzer, which examine economic and political-economy issues in the Mandate era and the State of Israel. Most of the studies were originally published in scholarly journals and collected volumes in English. Their revision and publication in Hebrew under one volume is aimed at making them more accessible to the Israeli readership. The book consists of nine chapters, grouped into three parts. The first part includes four chapters that present the main socio-economic attributes of the Arab and Jewish populations during the Mandate period and examine them in broad comparative frameworks. The three chapters of the second part take up ethno-national aspects of land and settlement in Mandatory Palestine and Israel, and analyze them in comparative perspective. The third part deals with patterns of immigration and employment of Jews as individuals. It contains two chapters. One documents the socio-demographic profile of the immigrants to Palestine in the first decade of the British Mandate, and compares it with the international migration of the time. The other chapter examines comparatively the patterns of Jewish self-employment in the Diaspora and in Mandatory Palestine and Israel, from the early twentieth century onward.
