Money-Back Guarantees and Market Experimentation (with W. Novshek)
- International Journal of Industrial Organization, vol. 22 (2004),
pp. 983-996.
We study the use of money-back guarantees as a form of market experimentation
in a market for experience goods with repeat purchases. We show that extending
the customer base in the second period by using a money-back guarantee can
be optimal only if a monopolist faces an uncertain distribution of buyers.
Within the second period, a money-back guarantee allows the monopolist to
discriminate between new and repeat purchasers while a pure price reduction
does not. Thus, whenever money-back guarantees are feasible, an optimal
experimentation strategy includes a money-back guarantee in the second period
but not necessarily a price reduction.
The Impact of Culture on the Purchase of Life Insurance in Latin America
and the Caribbean (with J. Eck) - International Business and Economics
Research Journal, 5, 1 (Jan 2006), pp. 31-45.
This study attempts to determine the major reasons for the lack of success
in marketing life insurance in Latin America and the Caribbean. Our results
point at the importance of cultural variables of which the most significant
is the percentage of the population that professes to be Catholic. We attribute
this to a strong correlation between religious beliefs and risk preferences.
The other major factor is the population's attitude toward financial instruments
in general. Both results are robust to the model specification. The findings
should be of interest to insurance companies attempting to market life insurance
throughout the world.
To Disclose or Not? An Analysis of Software User Behavior (with
M.Thursby) - Information Economics and Policy, 19 (1), 43-64.

Workshop on Economics of Information Security and an SSRN
working paper.
This paper addresses the ongoing debate over disclosing information about
software vulnerabilities through an open public forum. Using a game-theoretic
approach, we show that full public disclosure may be an equilibrium strategy
in a game played by rational loss-minimizing agents. We provide conditions
under which full public disclosure of vulnerabilities is desirable from
a social welfare standpoint. We analyze the effect of several vendor and
product characteristics and the composition of the pool of software users
on the decisions to disclose and on social welfare. We also examine models
in which users may spend effort to develop a fix or threaten vendors to
disclose after a grace period. We show that to the extent that users are
able to develop fixes for discovered vulnerabilities without inordinate
effort, welfare is further improved. This is more likely the more familiar
users are with the details of software providing an argument for "open
source" software.
Attackers' Motivation and Security Investment (with M.Cremonini)
In: Contributions in Game Theory and Management, School of Management,
St. Petersburg State University, Russia, 2007.
Earlier versions available as Washburn
School of Business Working Paper No. 68, and as 2006
Workshop on Economics of Information Security presentation.
We model economic behavior of attackers when they are able to obtain complete
information about the security characteristics of targets and when such
information is unavailable. We find that when attackers are able to distinguish
targets by their security characteristics and switch between multiple alternative
targets, the effect of a given security measure is stronger. That is due
to the fact that attackers rationally put more effort into attacking systems
with low security levels. Ignoring that effect would result in underinvestment
in security or misallocation of security resources. We also find that systems
with better levels of protection have stronger incentives to reveal their
security characteristics to attackers than poorly protected systems. Those
results have important implications for security practices and policy issues.
Risks and Benefits of Signaling Information System Characteristics to
Strategic Attackers (with M.Cremonini) - Journal Of Management Information
Systems, 26 (3), Winter 2010, pp. 241-274.
An earlier version is available as Washburn
School of Business Working Paper No. 95.
The paper uses a game-theoretic setting to examine the interaction between
strategic attackers who try to gain unauthorized access to information systems,
or "targets," and defenders of those targets. Our analysis of
the attacker-defender interaction shows that well- protected targets can
use signals of their superior level of protection as a deterrence tool.
This is due to the fact that, all other things being equal, rational attackers
motivated by potential financial gains tend to direct their effort toward
less-protected targets. We analyze several scenarios differing in the scope
of publicly available information about target parameters and discuss conditions
under which greater defenders ability to signal their security characteristics
may improve their welfare. Our results may assist security researchers in
devising better defense strategies through the use of deterrence and provide
new insight about the efficacy of specific security practices in complex
information security environments.
Work in progress:
- Reasons for Dumping, Demand Elasticity, and Exporter Responses to
Antidumping Sanctions (with A. Skiba)
The most recent version is available as 2010
International Industrial Organization Conference presentation.
When an anti-dumping duty is imposed, a foreign exporting firm can either
pay the duty or stop dumping by increasing the price of its product. An
importing countrys welfare depends on the foreign firms decision.
This paper presents a model of anti-dumping investigation which shows that
the exporters response crucially depends on the elasticity of import
demand. The firm is less likely to increase the price when the demand is
more elastic. Theoretical prediction is supported empirically by relating
product-level US import demand elasticities (estimated by Broda and Weinstein,
2006) and exporting firms reactions to duties inferred from a dataset
on U.S. antidumping investigations during 1980-1995.
