Dynamic specification of consumer expenditure on non-durables and services in Austria

Zusammenfassung Jüngste Fortschritte in der ökonometrischen Theorie führten zu erneutem Interesse an einem der am häufigsten analysierten Themenkreise der quantitativen Ökonomie: dem Zusammenhang zwischen Konsumausgaben und verfügbaren Einkommen. Entsprechende Tests ergaben, daß die Konsumausgaben für nichtdauerhafte Güter und Dienstleistungen und das verfügbare Einkommen kointegriert sind. Ausgehend von dieser Tatsache wurde in mehreren Schritten eine Konsumfunktion abgeleitet, die neben zufriedenstellenden statistischen Eigenschaften eine plausible ökonomische Interpretation zuläßt und eine interessante, mit den beobachteten Daten konsistente dynamische Struktur aufweist.

A theory of operational cash holding,endogenous financial constraints,and credit rationing

This paper develops a theory of operational cash holding. Liquidity shocks due to delayed payments must be financed using cash or short-term debt. Debt holders provide an irrevocable credit line given a firm's expected insolvency risk, and equity holders select optimum cash holding. The model demonstrates the trade-off between cash holding and investing in fixed assets. Introducing uncertain cash flows leads to precautionary cash holding if debt holders impose financial constraints. Precautionary cash holding, in turn, reduces insolvency risk enhancing access to short-term finance. The theory shows that credit rationing can occur in the absence of market frictions. Using U.S. data from 1998 to 2012, empirical findings suggest that the decline in credit lines has contributed to the increase in cash holding in line with theoretical predictions.     

The treatment of seasonality in error correction models as unobserved component: a case study for an Austrian consumption function

This paper deals with an alternative approach to treating seasonality in error correction models for consumption with a parsimonious parameterization as proposed by Harvey and Scott. We introduce an unobserved seasonal component into an error correction model for Austrian consumer expenditures on nondurables and services and compare the results with different approaches. The use of stochastic seasonal results in a definite improvement of the estimated model. First version received: October 1997/Final version received: May 2000     

Privacy Is Precious: On the Attempt to Lift Anonymity on the Internet to Increase Revenue

We investigate the effect of a reduction of anonymity on consumers' purchase decisions (whether to buy, and if so how much to pay) at an online music store with Pay‐What‐You‐Want (PWYW)‐like pricing and in an Internet experiment mimicking the real world situation. Revealing the customer's name, e‐mail, and payment to the artist (seller) led to insignificantly higher payments, although it drastically reduced the number of customers purchasing. Overall, the regime led to a revenue loss of 25%. In the online experiment, revenue drops by 35%. These results suggest that the positive effect of reduced anonymity, previously established for donation or public goods contexts, does not extend to a consumption environment. Instead, the substantial opt‐out of customers is likely to be motivated by concerns about privacy.
