Revising the conventional tax-effort principle

The standard methodology on tax-effort (i.e., the ratio of actual tax revenue to its optimal level) is to run a regression of actual tax revenue on countries’ specific (macroeconomic, demographic, geographical, political, social, and institutional) variables. The resulting predicted (fitted) values are then taken to represent the optimal (desired or maximum) level of tax revenue. The crucial issue of tracing out how the optimal tax revenue should be allocated to the fiscal objectives (equity, efficiency) does not seem to be of any interest to the researchers on tax-effort. The present paper argues that the standard methodology is not without faults and needs revising. We demonstrate that an optimal tax system can be safely derived from maximizing a utility function with respect to (in)direct tax rates. The manipulation of the first-order conditions, using a novel mathematical module, leads to an infinite number of optimal direct–indirect tax rates. The selection of the optimal mix of these tax rates is dependent on the country-specific households’ preferences over equity/efficiency, as they are formulated by voters’ volition in election periods. A simulation procedure helps understanding how the optimal tax revenue is chosen and how it can be optimally allocated to fiscal objectives, in the context of a panel data set including a large number of developed and developing countries. Throughout our text, the optimal tax revenue is defined as the sum of the products of the optimal (in)direct tax rates and their corresponding tax bases. In the simple Arrow–Debreu economy, the above sum is shown to be equal to the difference between income and consumption.     

Managing the customer horizon — final customers and the network perspective

Dealing with complex networks of inter-organisational exchanges remains a managerial challenge for business marketers. Incorporating the needs and wants of final customers into managerial considerations is often deemed impossible for companies with no direct exchange relationships with these final customers. For this reason, developing a value perspective of ‘interlocking customer horizons’ which include final customer considerations appears to be pivotal for generating insights into value-creating systems     

Changing network pictures: Evidence from mergers and acquisitions

A merger or acquisition may cause dramatic changes in a business network, which in turn affect managerial cognition as well as managerial activities. We use the concepts of ‘network pictures’ and ‘networking’ to illustrate and analyse changes in managerial sense-making and networking activities following a merger or acquisition. The paper focuses on acquiring, acquired or merging parties and those companies with which they have direct customer relationships. Based on three case studies comprising seven acquisitions and one merger, we show that following a merger or acquisition managers may need to adapt their previous network pictures in a radical way; these adaptations are, however, not always realized as shifts in network pictures and adjustments in networking activities by all the managers involved. Whereas the merging parties' network pictures and networking activities are largely driven by their perception of customers' needs and developments, it is not certain that the merger or acquisition is enacted accordingly. The paper contributes to a clearer view on the conceptual interdependence of the constructs of network pictures and networking in multi-actor situations and thus it develops a network perspective on mergers and acquisitions.     

State Dependence and Stickiness of Sovereign Credit Ratings: Evidence from a Panel of Countries

Using data from Moody's, we examine three sources of sovereign credit ratings persistence: true state dependence, spurious state dependence and serial error correlation. Accounting for ratings persistence, we also examine whether ratings were sticky or procyclical for two major crises: the European debt crisis and the East Asian crisis. We set up a dynamic panel ordered probit model with autocorrelated disturbances and nonparametrically distributed random effects. An efficient Markov chain Monte Carlo algorithm is designed for model estimation. We find evidence of stickiness of ratings and of the three sources of ratings persistence, with the true state dependence being weak. Copyright © 2015 John Wiley & Sons, Ltd.     

The constitution of networks

The idea of a constitution of networks may be a useful addition to our ways of understanding what happens within the business landscape. We describe a constitution of networks as a system of values, norms, rules and other conventions that are shared by actors in business networks. Whether by intention or not, the constitution of networks provides a framework within which interaction among actors takes place. We argue that companies invest in the selection and replication of interaction practices that evolve over time as customs or common use. This involves interaction aimed at developing or accessing resources for future use in the relationships between actors. In this way, the constitution of networks circumscribes the actors' appreciations and expectations about how they and others should conduct business.This study is based on empirical research conducted between 2002 and 2005 in business networks of consumer goods in the United Kingdom. Significant actors include multinational consumer goods companies, large grocery retailers, consumers and public authorities.     

Contract research today: Where do we stand?

New insights of empirical studies in contract research do not always conform to those that might be expected as a result of these theoretical studies. Much of the research into the nature and form of contracts has been of a theoretical nature and it is often referred as ‘relational contract’ or ‘incomplete contract’ theory. In comparison, a limited number of empirical studies have been undertaken. This paper will set out the findings of these two major streams of theoretical analysis of contracts and then contrast them with recent empirical research into ‘framework contracts’.     

Innovation in business networks: The role of leveraging resources

This study investigates how companies innovate in their business networks. We examine the role of leveraging resources in the context of retail brand paints within the do-it-yourself (DIY) paint industry, where the role of innovation is pertinent to achieve differentiation and create value. The study investigates innovation as a process of leveraging resources within business relationships. Research findings demonstrate that manufacturers and retailers jointly leverage resources to develop and launch innovative retail brands. Companies need to carefully address these resource-leveraging processes and assess their options in developing innovations that enable sustainable growth.
