This paper demonstrates that investor irrationality can be contagious across markets. Supplementing existing studies on resale option theory, we illustrate that warrant speculation could spill over to the underlying stock market. Our findings indicate that high turnover of underlying stocks is associated with previous day’s high unexpected turnover of warrants, or previous day’s larger price de...

This paper examines the importance of local knowledge spillovers for the innovative and economic performance of firms in a developing country context. Theoretical and empirical studies in advanced economies underline the significance of local knowledge spillovers for innovation. However, not much is known about whether local knowledge spillovers work similarly in developing countries. This anal...

This paper seeks to examine the paradox that despite the growing role of FDI in most economies and growth in their share of employment, exports and innovation (‘direct spillovers’), evidence of technological spillovers to domestic firms in the host economy (‘indirect spillovers’) is sparse. Given the explicit dependence of the development strategies of developing countries on FDI after liberali...

This paper examines the effects of IT-related spillovers on firm-level productivity improvements over a long-term horizon. In contrast, prior research has largely focused on the direct and contemporaneous impacts of IT investments. As a result, we do not fully understand how IT investments are associated with ongoing productivity improvements in future periods and how spillovers influence these...

Many public health interventions provide benefits that extend beyond their direct recipients and impact people in close physical or social proximity who did not directly receive the intervention themselves. A classic example of this phenomenon is the herd protection provided by many vaccines. If these 'spillover effects' (i.e. 'herd effects') are present in the same direction as the effects on ...

Using company account data for the US and four European countries this paper analyses the impact of ICT spillovers on companies’ performance. We use different definitions of spillovers to account for inter and intra-industry spillover effects, as well as assessing the presence of spillovers from the US to Europe. We also look at the possibility that spillovers might take some time to materialis...

This paper develops a new approach to identifying peer achievement spillovers in the context of an equilibrium model of student effort choices. By focusing on the effect of contemporaneous peer achievement, this framework integrates previously unexplored types of heterogeneity in peer spillovers in the achievement production context. Applying the strategy to North Carolina public elementary sch...

We analyse the impact of ICT spillovers on productivity using company data for the U.S. We account for interand intra-industry spillovers and assess the role played by firm’s absorptive capacity. Our results show that intra-industry ICT spillovers have a contemporaneous negative effect that turns positive 5 years after the initial investment. For inter-industry spillovers both contemporaneous a...

We explore mechanisms driving enforcement spillovers when sanctions at one entity influence behavior at other entities. Our model illustrates when spillovers arise from a regulatory channel and when they arise from a channel not emphasized in the existing literature: product markets. Using facility-by-month data from Clean Water Act manufacturers, we find that penalties generate strong positive...

In this paper we investigate the innovativeness of a network of firms, each of which can experience innovation spillovers (i.e. technological externalities) from its neighbours. A cellular automata framework is used to provide a new theoretical method for analysing such networks. Considering network spillovers produces a nonlinear relationship between the strength of spillovers and overall inno...
