Statistical Disclosure Control Methods for Census Frequency Tables

This paper provides a review of common statistical disclosure control (SDC) methods implemented at statistical agencies for standard tabular outputs containing whole population counts from a census (either enumerated or based on a register). These methods include record swapping on the microdata prior to its tabulation and rounding of entries in the tables after they are produced. The approach for assessing SDC methods is based on a disclosure risk–data utility framework and the need to find a balance between managing disclosure risk while maximizing the amount of information that can be released to users and ensuring high quality outputs. To carry out the analysis, quantitative measures of disclosure risk and data utility are defined and methods compared. Conclusions from the analysis show that record swapping as a sole SDC method leaves high probabilities of disclosure risk. Targeted record swapping lowers the disclosure risk, but there is more distortion of distributions. Small cell adjustments (rounding) give protection to census tables by eliminating small cells but only one set of variables and geographies can be disseminated in order to avoid disclosure by differencing nested tables. Full random rounding offers more protection against disclosure by differencing, but margins are typically rounded separately from the internal cells and tables are not additive. Rounding procedures protect against the perception of disclosure risk compared to record swapping since no small cells appear in the tables. Combining rounding with record swapping raises the level of protection but increases the loss of utility to census tabular outputs. For some statistical analysis, the combination of record swapping and rounding balances to some degree opposing effects that the methods have on the utility of the tables.

Market Structure and Foreign Direct Investment

During the last decade the extent of inward foreign direct investment (FDI) in the US has increased dramatically. An important aspect of industries where most FDI takes place is their high level of concentration. This paper investigates how strategic interactions among domestic and foreign producers influence the structure of the industry. Especially, it focuses on the foreign firms' choice between exporting versus servicing these markets by investing in a plant located in the host country when facing competition from a domestic oligopoly. The empirical investigation reveals that the relationship between FDI and tariffs is not as simple as previously thought. In highly concentrated industries, where strategic behavior may play an important role, high tariffs rather than low tariffs may lead to less FDI and more imports.     

How Much Is Investor Autonomy Worth?

There is a worldwide trend towards defined contribution savings plans, where investors are often able to select their own portfolios. How much is this freedom of choice worth? We present retirement investors with information about the distribution of outcomes they could expect to obtain from the portfolios they picked for themselves, and the same information for the median portfolio selected by their peers. A majority of our survey participants actually prefer the median portfolio to the one they picked for themselves. We investigate various explanations for these findings and offer some evidence that the results are partly attributable to the fact that investors do not have well‐defined preferences.     

Individual-rational and group-rational inflation expectations: Theory and cross-section evidence

A distinction is drawn between individual-rational and group-rational inflation expectations. Survey data for Israel show that individual inflation expectations are influenced by socioeconomic and psychological variables — specifically, interpersonal trust, age and income.     

Word of mouth activity as information search: A reappraisal

Studies on the diffusion of new products show that word-of-mouth activity WOMA) is an important influencer of consumer acceptance. WOMA has usually been defined primarily as information seeking behavior aimed at risk reduction prior to the purchase decision. To test this hypothesis, data on a new milk additive brand were used from a 1,100 state-wide sample conducted longitudinally. The findings were consistent in rejecting the hypothesis, therefore casting doubt on the exclusive information search nature of WOMA. The main implication is to view WOMA as a multiform communication activity including conversation types other than information search.     

Sociocultural Integration in Mergers and Acquisitions: Unresolved Paradoxes and Directions for Future Research

Despite decades of research, the key factors for success in mergers and acquisitions (M&As) and the reasons why M&As often fail remain poorly understood. While attempts to explain M&A success and failure have traditionally focused on strategic and financial factors, an emergent field of inquiry has been directed at the sociocultural and human resources issues involved in the integration of acquired or merging firms. This research has sought to explain M&A performance and underperformance in terms of the impact that variables such as cultural fit, management style similarity, the pattern of dominance between merging firms, the acquirer's degree of cultural tolerance, and the social climate surrounding a takeover have on the postmerger integration process. In this article, we attempt to take stock of, and synthesize, the findings from research on sociocultural and human resources integration in M&A, to identify conflicting perspectives and unresolved questions as well as several underresearched areas, and then use our analyses to propose an agenda for the next stage of research in this field. © 2013 Wiley Periodicals, Inc.     

Critical Success Factors through the Mergers and Acquisitions Process: Revealing Pre‐ and Post‐M&A Connections for Improved Performance

The mergers and acquisitions (M&A) literature is vast, spanning over half a century of research endeavor and drawing upon multiple disciplinary perspectives. Despite this wealth of material, the field suffers from a lack of connectedness. There is limited and compartmentalized understanding of the complexities of the M&A process, as the various streams of M&A research are only marginally informed by one another. As a result, the existing body of knowledge on M&A research remains fragmented. There is a need to establish links between existing approaches to M&A and the critical success factors they each promote. In this article, the need for a pluralistic and holistic explanatory framework that reflects the multidisciplinary nature of M&A is highlighted. The article shows that dynamic relationships between different perspectives on M&A and critical success factors matter. Identifying these relationships may help to further our understanding about M&A performance outcomes. Thus, the paper focuses on both relationships within each stage and between stages of the M&A process. © 2013 Wiley Periodicals, Inc.     

Project food aid and equitable growth: Income-transfer efficiency first!

This paper discusses the income transfer properties of food aid in order to shed light on the inputs necessary to ensure a contribution to equitable growth, particularly with reference to the alleviation of poverty and malnutrition. The author defines the concepts of income-transfer efficiency and nutrition efficiency and shows that food aid which is income-transfer efficient is usually also nutrition efficient. Some empirical evidence of the income-transfer efficiency of different commodities supplied to various countries is reviewed and policy implications for the selection of food aid commodities and projects are discussed. The author concludes with some working propositions designed to stimulate further debate on the selection and administration of food aid projects.
