Experimental asset markets with endogenous choice of costly asymmetric information
- 2011

Tidskriftsartikel (refereegranskat)abstract
- Asymmetric distribution of information, while omnipresent in real markets, is rarely considered in experimental financial markets. We present results from experiments where subjects endogenously choose between five information levels (four of them costly). We find that (i) uninformed traders earn the highest net returns, while average informed traders always perform worst even when information costs are not considered; (ii) over time traders learn to pick the most advantageous information levels (full information or no information); and (iii) market efficiency decreases with higher information costs. These results are mostly in line with the theoretical predictions of Grossman and Stiglitz (Am. Econ. Rev. 70:393–408, 1980) and provide additional insights that studies with only two information levels cannot deliver.

Is more information always better? Experimental financial markets with cumulative information
- 2008

Ingår i: Journal of Economic Behavior and Organization. - 0167-2681. ; 65:1, s. 86-104

Tidskriftsartikel (refereegranskat)abstract
- We study the value of information in financial markets by asking whether having more information always leads to higher returns. We address this question in an experiment where information about an asset's intrinsic value is cumulatively distributed among traders. We find that only the very best informed traders (i.e., insiders) significantly outperform less informed traders. However, there is a wide range of information levels (from zero information to above average information levels) where additional information does not yield higher returns. The latter result implies that the value of additional information need not be strictly positive.

The impact of a financial transaction tax on stylized facts of price returns-Evidence from the lab
- 2012

- As the introduction of financial transaction taxes is increasingly discussed by political leaders we explore possible consequences such taxes could have on markets. Here we examine how "stylized facts", namely fat tails and volatility clustering, are affected by different tax regimes in laboratory experiments. We find that leptokurtosis of price returns is highest and clustered volatility is weakest in unilaterally taxed markets (where tax havens exist). Instead, tails are slimmest and volatility clustering is strongest in tax havens. When an encompassing financial transaction tax is levied, stylized facts hardly change compared to a scenario with no tax on all markets. (C) 2012 Elsevier B.V. All rights reserved.

The impact of instructions and procedure on reducing confusion and bubbles in experimental asset markets
- 2012

Tidskriftsartikel (refereegranskat)abstract
- In 1988 Smith, Suchanek, and Williams (henceforth SSW) introduced a very influential model to test the efficiency of experimental asset markets. They and many subsequent studies observe that bubbles are robust to many treatment changes. Instead, bubbles are avoided only when subjects are experienced in the same setting, when the dividend-process is experienced by subjects beforehand, or when the fundamental value-process (FV) is presented in a well understandable context to reduce subjects’ confusion. We extend this line of research and show that even marginal changes in the experimental instructions/procedure can eliminate bubbles in the SSW-model. In particular, we show that mispricing is significantly reduced and overvaluation is eliminated completely (i) when the fundamental value process is displayed in a graph instead of a table or (ii) when subjects are asked about the current fundamental value at the beginning of each period. From a questionnaire conducted at the end of the experiment we infer that these treatment changes help to improve subjects’ understanding of the FV-process. We conclude that all bubble reducing factors have one common feature: they allow subjects to understand the non-intuitive declining FV-process of the SSW-model better and thus reduce subjects’ confusion about the FV-process.

The influence of investment experience on market prices: laboratory evidence
- 2016
-
Ingår i: Experimental Economics. - : Springer Science and Business Media LLC. - 1386-4157 .- 1573-6938. ; 19:2, s. 394-411

Tidskriftsartikel (refereegranskat)abstract
- We run laboratory experiments to analyze the impact of prior investment experience on price efficiency in asset markets. Before subjects enter the asset market they gain either no, positive, or negative investment experience in an investment game. To get a comprehensive picture about the role of experience we implement two asset market designs. One is prone to inefficient pricing, exhibiting bubble and crash patterns, while the other exhibits efficient pricing. We find that (i) both, positive and negative, experience gained in the investment game lead to efficient pricing in both market settings. Further, we show that (ii) the experience effect dominates potential effects triggered by positive and negative sentiment generated by the investment game. We conjecture that experiencing changing price paths in the investment game can create a higher sensibility on changing fundamentals (through higher salience) among subjects in the subsequently run asset market.

Market microstructure matters when imposing a Tobin tax-Evidence from the lab
- 2011
-
Ingår i: Journal of Economic Behavior & Organization. - 0167-2681. ; 80:3, s. 586-602
-
Tidskriftsartikel (refereegranskat)abstract
- Trading in FX markets is dominated by two microstructures: exchanges with market makers and OTC-markets without market makers. Using laboratory experiments we test whether the impact of a Tobin tax is different in these two market microstructures. We find that (i) in markets without market makers an unilaterally imposed Tobin tax (i.e. a tax haven exists) increases volatility. (ii) In contrast, in markets with market makers we observe a decrease in volatility in unilaterally taxed markets. (iii) An encompassing Tobin tax has no impact on volatility in either setting. Efficiency does not vary significantly across tax regimes.

Bubble measures in experimental asset markets
- 2010
-
Ingår i: EXPERIMENTAL ECONOMICS. - 1386-4157. ; 13:3, s. 284-298
-
Tidskriftsartikel (refereegranskat)abstract
- We review bubble measures which are commonly used in the experimental asset market literature. It seems sensible to require that measures of mispricing should (i) relate the fundamental value and price, (ii) be monotone in the difference between fundamental value and price, and (iii) be independent of the total number of periods and the absolute level of fundamental value. We show that none of the measures currently used fulfills all these criteria. To facilitate comparability across different experimental settings with different parameterizations we propose two alternative measures which fulfill all evaluation criteria. The measure for mispricing, RAD (relative absolute deviation), is calculated by averaging absolute differences between the (volume-weighted) mean price and the fundamental value across all periods and normalizing it with the absolute value of the average FV of the market. The measure for overvaluation, RD (relative deviation), is calculated analogously, but uses raw difference between (volume-weighted) mean prices and fundamental values. Hence, it provides information on whether the mispricing stems from over- or undervaluation of the asset.
