When financial work incentives pay for themselves: evidence from a randomized social experiment for welfare recipients

This paper summarizes early findings from a social experiment that provided financial incentives for new welfare recipients to leave welfare and work full time. The financial incentive was essentially a negative income tax with a requirement that people work at least 30 h/week. Early results show that the financial incentive increased full-time employment, earnings, and income, and reduced poverty. Furthermore, at the end of the period discussed in this paper, the program was paying for itself through increased tax revenues.     

Entry and Vertical Differentiation

This paper analyzes the entry of new products into vertically differentiated markets where an entrant and an incumbent compete in quantities. The value of the new product is initially uncertain and new information is generated through purchases in the market. We derive the (unique) Markov perfect equilibrium of the infinite horizon game under the strong long run average payoff criterion. The qualitative features of the optimal entry strategy are shown to depend exclusively on the relative ranking of established and new products based on current beliefs. Superior products are launched relatively slowly and at high initial prices whereas substitutes for existing products are launched aggressively at low initial prices. The robustness of these results with respect to different model specifications is discussed. Journal of Economic Literature Classification Numbers: C72, C73, D43, D83.     

Entrepreneurial orientation‐as‐experimentation and firm performance: The enabling role of absorptive capacity

According to the perspective of entrepreneurial orientation‐as‐experimentation, entrepreneurial orientation (EO) increases variability in innovation outcomes. Although increased variability in the innovation portfolio could increase performance, it could also lead to a decline in performance. We propose that absorptive capacity plays a role in both increasing and managing variations in innovation outcomes. Potential absorptive capacity enhances the effects of EO on variability in innovation outcomes, whereas realized absorptive capacity helps transform and exploit variability in innovation outcomes to enhance firm performance.
