We develop a dynamic politico-economic theory of welfare state and immigration policies, featuring three groups of voters: skilled workers, unskilled workers, and old retirees. The welfare-state is modeled by a proportional tax on labor income to finance a demogrant in a balanced-budget manner...

We develop a dynamic politico-economic theory of welfare state, featuring three groups of voters: skilled workers, unskilled workers, and old retirees. The welfare-state is modeled by a proportional tax on labor income to finance a demogrant in a balanced-budget manner to capture the essence of...

The Internet comprises thousands of independently operated networks, where bilaterally negotiated interconnection agreements determine the flow of data between networks. The European Union's General Data Protection Regulation (GDPR) imposes strict restrictions on processing and sharing of...

New security designs, improvements in computer telecommunications technology and advances in the theory of finance have led to revolutionary changes in the structure of financial markets and institutions. This paper provides a functional perspective on the dynamics of institutional change and...

This paper studies how demand for labor reacts to financial technology (fintech) shocks based on comprehensive databases of fintech patents and firm job postings in the U.S. during the past decade.

We ask whether epidemic exposure leads to a shift in financial technology usage within and across countries and if so who participates in this shift. We exploit a dataset combining Gallup World Polls and Global Findex surveys for some 250,000 individuals in 140 countries, merging them with...

The paper provides an overview of cryptocurrencies and decentralized finance. The discussion lays out potential benefits and challenges of the new system and presents a comparison to the traditional system of financial intermediation. Our analysis highlights that while the DeFi architecture...

A binding interest rate cap on household savings is a common form of financial repression in developing economies and typically benefits banks. Using proprietary data from a leading Chinese FinTech company, we study Fintech's role in ending financial repression in China through the introduction...

This paper studies the economic role of financial institutions in economies where agents' incomes are subject to privately observable, idiosyncratic random events. The information structure precludes conventional insurance arrangements. However, a financial institution -- perhaps best viewed as...
