Roadmapping: (Missed) opportunities to overcome strategic challenges

Firms face various critical challenges when pursuing a coherent course of action that seeks to create value for the long term. They are required to balance myopic and hyperopic behavior. They must ensure coordination, adopt a holistic view of various functional perspectives, and foster commitment among key decision makers. They need to develop a credible and compelling line of reasoning that employees understand and can act on. Adopting the perspective of roadmapping as a strategy tool, this article advances the argument that roadmapping is especially suitable in helping firms to surmount these three critical strategic challenges. This article distills three core features of the roadmap: graphical representation, multi-disciplinary integration, and scaling. It then reviews the three critical strategic challenges and shows how roadmapping can help to overcome each of these. Following this explanation, the article describes ten key principles for effective strategic roadmapping that support firms in obtaining the strategic benefits promised. The article concludes with additional insights for practice with the intent of encouraging further exploitation of roadmapping’s potential.     

Wage Differentials and Workers’ Effort: Experimental Evidence from Uganda

We organize a real-effort field experiment with varying piece rates to assess the impact of wages and social comparisons on productivity. In addition to analyzing how piece rates and social comparisons affect productivity during the ‘paid stage’ of the experiment, we also consider how they affect effort supply during a voluntary and unpaid follow-up task. Our main results are that effort supply is relatively unresponsive to variation in own earnings, but responds strongly to pay inequality. While we obtain weak support for the hypothesis that positive social comparisons invite extra effort during paid stages of the experiment, our most important finding is that social comparisons matter for voluntary tasks when shirking is cheap. Specifically, positive social comparisons positively affect productivity during unpaid tasks, and negative comparisons have the opposite impact.     

The adaptive efficiency of land use planning measured by the control of urban sprawl. The cases of the Netherlands,Belgium and Poland

The paper aims to position the concept of adaptive efficiency in planning theory, by providing insights on the conditions that explain why land use planning in some institutional contexts is able to adapt and improve more efficiently than in others. This is done by focusing on a specific planning goal: the control of residential sprawl. The paper presents a theoretical framework based on two models, one on the coordinating mechanisms regarding the use of land and one to explain institutional changes. This framework is exploited with empirical case studies where we compare the control of sprawl in the Netherlands, Belgium and Poland. The analysis diagnoses a duality of planning practices. Even though planning failures occur in the Netherlands as well, we provide evidence that Dutch land use planning has been able to efficiently adapt regulatory instruments and collaborative practices to societal changes. By contrast, Belgian and Polish planners face huge difficulties to incorporate new initiatives to control urban sprawl or, in more general terms, to reinforce their influence on land uses.     

Schumpeter: Theorist of the avant-garde

This paper argues that Schumpeter’s 1911 edition of ‘Theory of Economic Development’ can be fruitfully read as a theory of the avant-garde, in line with such theories developed by artistic avant-garde around the same time, in particular by the Italian Futurists. In particular it will show that both Schumpeter and other avant-garde theorists sought to break with past (1), identify an avant-garde who could force that break (2), find new ways to represent the dynamic world (3), embrace the new and dynamic (4) and promote a perpetual dynamic process, instead of a specific end-state or utopia (5). This new reading helps us to understand the cultural meaning of this seminal text in economics. Secondly it greatly facilitates our understanding of the differences with the later interwar German edition and English edition, which were more cautious in their embrace of the new, less focused on the individual qualities of the entrepreneur and placed more emphasis on historical continuity. Thirdly this reading suggests a different reason for the bifurcation between Schumpeter and the rest of the Austrian school of economics. Traditionally this split is explained by Schumpeter’s affinities with the Lausanne School, this paper instead suggests that the crucial break between Schumpeter on the one hand and Böhm-Bawerk, Wieser and later members of the Austrian School on the other hand is their theory of and attitude toward social change.     

Decompositions of profitability change using cost functions

The paper presents a decomposition of a production unit’s cost ratio over two periods into explanatory factors. The explanatory factors are growth in the unit’s cost efficiency, output growth, changes in input prices and technical progress. In order to implement the decomposition, an estimate of the industry’s best practice cost function for the two periods under consideration is required. Profitability at a period of time is defined as the value of outputs produced by a production unit divided by the corresponding cost. Using the earlier work by Balk and O’Donnell, the paper provides a decomposition of profitability growth over two periods into various explanatory factors that are similar to the cost ratio decomposition except that change in outputs explanatory factor is replaced by two separate factors: an index of output price growth and a measure of returns to scale.     

Malmquist and Törnqvist productivity indexes: returns to scale and technical progress with imperfect competition

Caves, Christensen and Diewert proposed a method for estimating a theoretical productivity index for a firm using Törnqvist input and output indexes, augmented by exogenous estimates of local returns to scale. However, in order to implement their method, they assumed that the firm maximized revenue in each period, conditional on the observed input vector in each period, taking output prices as fixed. This assumption is not warranted when there are increasing returns to scale. Thus in the present paper, it is assumed that the firm solves a monopolistic profit maximization problem when there are increasing returns to scale and the results of Caves, Christensen and Diewert are modified in accordance with this assumption.     

Product innovativeness from the firm's perspective: Its dimensions and their relation with project selection and performance

There has recently been tremendous interest in product innovativeness. However, it seems that we need a better understanding of exactly what product innovativeness means. This article presents a conceptual framework to clarify its meaning. The framework first distinguishes customer and firm perspectives on product innovativeness. From the customer's perspective, innovation attributes, adoption risks, and levels of change in established behavior patterns are regarded as forms of product newness. Within the firm's perspective, environmental familiarity and project-firm fit, and technological and marketing aspects are proposed as dimensions of product innovativeness.
Next, the article offers a tentative empirical test of the proposed dimensions of product innovativeness from the firm's perspective. A well-known dataset of 262 industrial new product projects is used to: I) clarify the product innovativeness construct and examine its underlying dimensions, 2) examine the relation of product innovativeness with the decision to pursue or kill the project, and 3) examine the relationship between product innovativeness and product performance. Five dimensions of product innovativeness are found which have distinct relations with the Go/No Go decision and product performance: market familiarity, technological familiarity, marketing fit, technological fit, and new marketing activities. Most strikingly, measures of fit are related to product performance, whereas measures of familiarity are not.
The article concludes that researchers need to be careful about which definitions and measures of product innovativeness they employ, because depending on their choice they may arrive at different findings. New product practitioners are encouraged to evaluate new product opportunities primarily in terms of their fit with their firm's resources and skills rather than the extent to which they are "close to home".     

Great expectations: Banks as equity underwriters

We examine the in-roads commercial banks have made into equity underwriting over 1990–2002. While banks end the period handling upwards of 25% of equity underwriting, this increase results almost exclusively from acquisitions of investment banks with an already established market share of equity underwriting. We find a significant decline in the market share of equity underwriting that banks acquired in the post-merger period, a decline that is larger than that experienced by independent investment banks of comparable reputation. Banks lose market share because they originate fewer IPOs and their IPOs have a lower incidence of follow-on SEOs compared to independent investment banks. Following the merger, banks experience a large fall off in their ability to retain follow-on SEOs and are less successful in winning SEO mandates when an issuer switches from its IPO underwriter. Overall, the findings suggest it has been difficult for banks to achieve scope economies in equity underwriting.     

A game theory approach to the analysis of land and property development processes

Land and property development processes obviously can be seen as a social situation in which the interaction of individuals or groups of individuals is one of the essential elements. To study and understand social situations, it is important to analyse how the decisions of actors are interrelated and how those decisions result in outcomes. In this paper, we propose a game theoretical modelling approach to analyse it. Hence, the objective of the paper is to investigate the usefulness as well as the limitations of game theoretical modelling for analysing and predicting the behaviour of actors in decision-making processes with respect to the development of land and property. For that purpose, we have developed game models for the case study of the development of a greenfield residential location in the Netherlands with respect to the implementation of new Dutch legislation on cost recovery.     

An analysis of housing expenditure using semiparametric cross-section models

In this paper we model expenditure on housing for owners and renters by means of endogenous switching regression models using cross-section data. We explain the share of housing in total expenditure from family characteristics and total expenditure, where the latter is allowed to be endogenous. We apply various existing parametric and semiparametric techniques for cross-section data. Exogeneity of total expenditure is rejected for the parametric models but not for most semiparametric models. The results are compared on the basis of budget elasticities and graphs of the estimated relationship between the budget share spent on housing and the logarithm of total expenditure.
