The Impact of Constitutional Protection of Economic Rights on Entrepreneurship: A Taxonomic Survey highlights how characteristics of the legal infrastructure of a country can create conditions that enhance new business creation. It is an exploration of the institutional determinants of entrepreneurship and the way these can affect the observed cross-country differences in the creation of new firms. The main aim is to analyze 195 constitutions, singling out the provisions that enhance economic freedom and are thus likely to create an institutional and legal setup favorable to new business creation. The study tries to answer a question of primary importance for the analysis of entrepreneurship. Does the constitutional protection of principles and values usually associated with a country’s endowment of entrepreneurship capital and presence of small firms positively influence the rate of new firm formation and the total endowment of entrepreneurship capital in that country? The remainder of this monograph is structured as follows. Section 2 discusses the importance of institutions in shaping the entrepreneurship capital of a country and favoring the emergence of entrepreneurial ecosystems. Section 3 describes how higher-rank formal institutions represented by actual constitutional provisions affect the design of lower rank norms and regulations of primary importance for economic activity. Section 4 outlines the features of ‘economic constitutions’, i.e. of constitutional provisions playing a key role in the management of a country’s economy. Section 5 gives an overview of alternative measures of entrepreneurship and discusses their implications for empirical analysis. Section 6 focuses on the countries that have adopted the principles of ‘economic constitutions’ in their written constitutions and discusses the impact of the de jure and de facto implementation of such principles on entrepreneurship. Section 7 shows how the prevailing psychological traits of a country’s population may shape the impact of constitutional provisions on its proneness to entrepreneurship and sheds light on the relationship between constitutional provisions and the observed cross-country and cross-industry differences in labor productivity. Finally, Section 8 concludes and provides some recommendations for entrepreneurship policy.
