Debt and managerial rents in a real-options model of the firm

We present a theory of capital investment and debt and equity financing in a real-options model of a public corporation. The theory assumes that managers maximize the present value of their future compensation (managerial rents), subject to constraints imposed by outside shareholders’ property rights to the firm's assets. Absent bankruptcy costs, managers follow an optimal debt policy that generates efficient investment and disinvestment. We show how bankruptcy costs can distort both investment and disinvestment. We also show how managers’ personal wealth constraints can lead to delayed investment and increased reliance on debt financing. Changes in cash flow can cause changes in investment by tightening or loosening the wealth constraints. Firms with weaker investor protection adopt higher debt levels.     

The economic value of patent portfolios

Patent holders may choose to protect innovations with single patents or to develop portfolios of multiple, related patents. We propose a decision‐making model in which patent holders allocate resources to either expanding the number of related patents or investing in higher value of patents in the portfolio. We estimate the derived value equation using portfolio value data from an inventor survey at the level of individual inventions rather than the firm as a whole. We find that investments in individual inventions exhibit diminishing returns, and that a good part of the value of a portfolio depends on adding new patented inventions. Also, while diminishing returns to individual inventions are stable across subsamples, the returns to portfolio size vary between complex and discrete industries, and between inventions that are science‐based or driven by customer information. When firms seek to strengthen appropriability, the returns to an increase of portfolio size are not different from the sample average. Thus, a higher number of inventions in a portfolio may reflect both stronger appropriability via patents and genuine creation of value.     

A flexible adaptation of the WIOD database in a virtual laboratory

ABSTRACT

The World Input-Output Database provides a time series of world input–output tables (WIOTs) that have been used for example to understand the manifold effects of the increased integration of markets through international trade. In order to enhance the flexibility of research on global trade issues using WIOD, we implement the WIOT workflow in a collaborative, cloud-based virtual laboratory environment. We demonstrate that a lab-based adaptation of WIOD is able (a) to continuously create and update versions of the WIOTs in a timely, consistent, and cost-effective way, (b) to enhance original information with accompanying information on standard deviations, and (c) to enable flexible re-casting of the entire WIOT time series into user-specific geographical and sectoral classifications.     

Consumers' Search for Information on the Internet: How and Why China Differs from Western Europe

Internet adoption in China is booming and purchasing power is growing steadily. Increasing numbers of Chinese turn to the Internet to search for information prior to a purchase. Based on 32 h of interviews with students and business professionals in China, and a questionnaire completed by a sample of 1140 students in Beijing and Belgium, our explorative study demonstrates that fundamental cultural, behavioral, economic, technical, and other characteristics of China cause significant differences between Chinese and Western Europeans in their online search process for information prior to a purchase. The differences occur in frequency, goal, types of information sought, types of websites used, search engine usage patterns, and contribution of user opinions. This has important implications for marketing practitioners in China, especially for multinational corporations that enter China and that are not familiar yet with the Chinese environment. Suggestions for future research are also provided.     

Use Tables for Imported Goods and Valuation Matrices for Trade Margins—an Integrated Approach for the Compilation of the Belgian 1995 Input–Output Tables

This paper describes the compilation of the use table for imported goods and the valuation matrix of trade margins for Belgium in 1995. It introduces the methodological novelty of integrating the compilation of both tables and systematically exploiting the fact that large import and export flows do not generate trade margins. This is notably the case for direct imports for intermediate consumption or investment by non-traders, and direct exports by producers. For identifying these trade flows, extensive use was made of intrastat and extrastat data. The results are compared with those of a proportional distribution of imports and trade margins. Many statistical offices resort to the latter approach because of a lack of survey data on the destination of trade margins and imports. We demonstrate that the integrated approach can improve the quality of both the import matrix and the valuation matrix for trade margins, while using only existing data sources.     

How and when is dual trading irrelevant?

Within a general model of speculative trade, we derive the aggregate consequences of dual traders who process retail liquidity trades and trade on their own account. We prove that dual trading reduces total expected speculator profits unless speculators process all liquidity trade and trade with the same intensity on liquidity trade. In contrast, dual trading does not affect the information content of prices. We show how results generalize when we endogenize (a) speculator information via costly information acquisition about fundamentals or costly processing of liquidity trade, and (b) liquidity trader motives and welfare via endowment shocks.
