We investigate the effect of the volunteering of others on the likelihood that an individual will also engage in volunteering activities. The theoretical part of our analysis is based on a sequential signaling framework, in which the decisions of others to volunteer are informative as to the...

Safety nets may reduce incentives to mitigate risks, and adversely affect people’s behavior. We model the safety net problem as a social dilemma game involving moral hazard, risk taking and limited liability. Individuals take costly measures to avoid a likely loss which, if incurred, is...

We analyze voluntary private contributions to public goods and the role seed money plays in signaling the public good's quality to potential subsequent contributors. We present a theoretical model and analyze two sets of naturally occurring data from crowd-funding platforms. After developing the...

This note focuses on the design of prevention programmes and the role of tort law regarding the control of risky activities, associated with unknown or imperfectly known risks, such as innovation or (long term) environmental damages. Together with the existence of perception bias on the side of...

The electronic communication market is currently in a phase of pure transition as it shifts from obsolete copper network and classical business models to Next Generation Networks (NGN) that use the same infrastructure to enable the widespread distribution of different services (voice, data, TV),...

In most modern economies scientific and technological research activities are conducted in two distinct organizational modes: commercially oriented R&D based upon proprietary information, and noncommercial “open science.” When taken together and kept in proper balance, these form a...

This note focuses on the design of prevention programmes and the role of tort law regarding the control of risky activities, associated with unknown or imperfectly known risks, such as innovation or (long term) environmental damages. Together with the existence of perception bias on the side of...

We model the safety net problem as a social dilemma game involving moral hazard, risk taking and limited liability. The safety net game is compared to both an individual decision task involving full liability and the deterministic public goods game. We report experimental data to show that...

In this analysis, we examine the relationship between an individual's decision to volunteer and the average level of volunteering in the community where the individual resides. Our theoretical model is based on a coordination game , in which volunteering by others is informative regarding the...

We examine the effect of endogenous and exogenous risk on the equilibrium (expected) membership of an International Environmental Agreement when countries are risk averse. Endogenous risk arises when countries use mixed rather than pure strategies at the participation game, and exogenous risk...
