Individual differences in performance when solving spatial tasks can be partly explained by differences in the strategies used. Two main difficulties arise when studying such strategies: the identification of the strategy itself and the stability of the strategy over time. In the present study strategies were separated into three categories: segmented (analytic), holistic-feedback dependent, and holistic-planned, according to the procedure described by Peña, Contreras, Shih, and Santacreu (2008) . A group of individuals were evaluated twice on a 1-year test-retest basis. During the 1-year interval between tests, the participants were not able to prepare for the specific test used in this study or similar ones. It was found that 60% of the individuals kept the same strategy throughout the tests. When strategy changes did occur, they were usually due to a better strategy. These results prove the robustness of using strategy-based procedures for studying individual differences in spatial tasks.

Role Of Information

In housing markets there is a trade-off between selling time and selling price, with pricing strategy being the balancing act between the two. Motivated by the Home Report scheme in Scotland, this paper investigates the role of information symmetry played in such a trade-off. Empirically, this study tests if sellers’ pricing strategy changes when more information becomes available and whether this, in turn, affects the trade-off between the selling price and selling time. Using housing transaction data of North-East Scotland between 1998Q2 and 2018Q2, the findings show that asking price has converged to the predicted price of the property since the introduction of the Home Report. While information transparency reduces the effect of ‘overpricing’ on selling time, there is little evidence to show that it reduces the impact of pricing strategy on the final selling price in the sealed-bid context.

Strategy Changes

This study examines how firms in the pharmaceutical industry responded to the R&D tax credit which was enacted in 1981. The change in research intensity (research/sales) subsequent to the tax change was estimated for the firms. An increase in research intensity was associated with the adoption of the tax credit. The strong response by the firms to the tax credit and the effort to maintain their relative position in research intensity indicate that research intensity is an important strategic dimension and driving force in the industry.

We study the effects of networking on the extent of cooperation emerging in an evolutionary snowdrift game, which is a possible alternative to the well-known Prisoner's Dilemma game. The model is studied in the Newman-Watts network that spans the regular, small-world, and random networks through randomly added links. For a wide range of payoffs, the added links are found to suppress cooperation, when compared with a well-mixed or fully connected system. We identify extinction payoffs that characterize the emergence of a homogeneous steady state and study how these payoffs depend on the extent of addition of links to the network.
