China and India, two Asian countries that experienced a rapid decline in fertility since the middle of the twentieth century, are the focus of this paper. Although there is no doubt that lower fertility levels have many positive effects on the economy, development and sustainability, little is...

In a pathbreaking paper Keyfitz (1971) calculated the demographic momentum, i.e. the amount of further population growth if an immediate reduction of fertility to bare replacement would occur. While he assumes a stable initial population, our research aims to extend it to so-called pseudostable...

This paper studies a three player hierarchical differential game (with a large country, a small country, and a terrorist organization), to analyze the actual European refugee situation. Terrorists may enter Europe as refugees, taking advantage of the Open Door Policy, to attack both countries....

This paper investigates, both theoretically and empirically, the implications that complementary assets needed for the formation of start-ups - proxied by the ease of access to financial resources - have on the innovative efforts of incumbent firms. In particular, we develop a theoretical model,...

We consider a simple dynamic model of environmental taxation that exhibits time inconsistency. There are two categories of firms, Believers, who take the tax announcements made by the Regulator to face value, and Non-Believers, who perfectly anticipate the Regulator's decisions, albeit at a...

This paper investigates, both theoretically and empirically, the implications that complementary assets needed for the formation of start-ups - proxied by the ease of access to financial resources - have on the innovative efforts of incumbent firms. In particular, we develop a theoretical model,...

We study investments in R&D and the formation of R&D clusters of firms which are competitors in the market. In a three stage game, firms first decide on long-term R&D investment, then form research clusters according to the unanimity game introduced in Bloch(1995), and finally compete in...

While the extant innovation literature has provided extensive evidence of the so-called "demand-pull" effect, the possible diverse impact of demand evolution on product vs process innovation activities has not been yet investigated. This paper develops a formal model predicting a larger inducing...

This paper addresses the role of product liability for the emergence and development of smart products such as autonomous vehicles (AVs). We analyze how the liability regime affects innovative activities, as well as the timing of market introduction and market penetration of such smart products....

We analyze the effect of external financing and associated bankruptcy threat on the speed of product innovation in a market characterized by technological and demand uncertainty. In a dynamic market setting we characterize the optimal R&D investment strategy of a monopolistic incumbent firm that...
