Search costs and efficiency: Do unemployed workers search enough?

Many labor market policies affect the marginal benefits and costs of job search. The impact and desirability of such policies depend on the distribution of search costs. In this paper, we provide an equilibrium framework for identifying the distribution of search costs and we apply it to the Dutch labor market. In our model, the wage distribution, job search intensities, and firm entry are simultaneously determined in market equilibrium. Given the distribution of search intensities (which we directly observe), we calibrate the search cost distribution and the flow value of non-market time; these values are then used to derive the socially optimal firm entry rates and distribution of job search intensities. From a social point of view, some unemployed workers search too little due to a hold-up problem, while other unemployed workers search too much due to coordination frictions and rent-seeking behavior. Our results indicate that jointly increasing unemployment benefits and the sanctions for unemployed workers who do not search at all can be welfare-improving.

The role of internationalization on the IPO performance of service firms: Examination of initial returns,long-run returns,and survivability

This study examines the effect of internationalization on the initial and long-run IPO performance of service firms. The study discusses that pre-IPO internationalization of service firms contributes to the explanation of long-discussed IPO underpricing phenomenon, and underperformance of IPOs in the long-run. Sample of the study includes 1822 IPO issues conducted by US service firms between 1980 and 2009. Findings of the study suggest that international service firms leave less money on table in their IPOs compared to domestic service firms by providing significantly lower first day returns to their investors on their first day of public trading. Moreover, our findings provide evidence that 3-year cumulative abnormal returns and 3-year buy-and-hold returns of international service firms are significantly higher than domestic service firms, and international service firms outperform domestic service firms in both operating return on assets and operating cash flows in the post-IPO period. Lastly, the study documents that survival rate of service firms subsequent to an IPO issue increases with pre-IPO internationalization.     

Accounting for age in marital search decisions

Spouse quality, measured by educational attainment, varies significantly with the age at which an individual marries, peaking in the mid-twenties then declining through the early-forties. Interestingly, this decline is much sharper for women than men, meaning women increasingly marry less educated men as they age. Moreover, quality has worsened for educated women over several decades, while it has improved for men. Using a non-stationary sequential search model, we identify and quantify the search frictions that generate these age-dependent marriage outcomes. We find that single-life utility is typically the dominant friction, though college women in the 1950 and 1970 cohorts are affected even more by deteriorating suitor quality. Regardless of educational status, individual choice (as opposed to pure luck) is pivotal in explaining marriage market outcomes earlier in life.     

Information rigidities and the news-adjusted output gap

A vector-autoregressive model of actual output and expected output obtained from surveys is used to test for information rigidities and to provide a characterisation of output dynamics that accommodates these information structures. News on actual and expected outputs is decomposed to identify innovations understood to have short-lived effects and these are used with the model to derive a ‘news-adjusted output gap׳ measure. The approach is applied to US data over 1970q1–2014q2 and the new gap measure is shown to provide a good leading indicator of inflation.     

Cross-market information transfers of ADR firms: An investigation of emerging market economies

Level II and III ADRs permit issuers to be listed on the major U.S. exchanges with the stipulation that they comply with extensive SEC disclosure requirements. Foreign private issuers are compelled to file a set of audited financial statements prepared in accordance with U.S. GAAP, or alternatively, IFRS or Home Country Accounting Principles with attendant reconciliation to U.S. GAAP prior to 2008. Although the Form 20-F reconciliation is discontinued in 2008 for IFRS filers, non-U.S. issuers are required to satisfy other Form 20-F stipulations such as expanded Item 17 and Item 18 disclosures. We conjecture that non-U.S. firms choosing to be listed on the major U.S. exchanges will incur the added costs associated with the supplemental disclosure requirements in order to attract sufficient investor attention as to have the disclosures impounded in the home country equity share price in the manner described by Fishman et al. (1989). Because a prominent attribute of ADR firms is that they benefit from multiple-market trading, we investigate whether the Form 20-F disclosure cross-market information transfers are associated with emerging market economy status. We employ models of the cross-market ADR and equity security share returns and trading volume controlling for the emerging economy status and incremental firm-specific SEC Form 20-F accounting principles disclosures. Preliminary results indicate that (1) U.S. listed ADR firms from emerging economies experience greater cross-market information transfers associated with the SEC Form 20-F filing, and (2) that the increased cross-market information transfers associated with the SEC Form 20-F filing are proportional to the difference in quality of accounting principles employed for home country reporting purposes vis-à-vis the accounting principles employed for SEC Form 20-F reporting purposes. Results are consistent with a feedback process through which the new information disclosed by the SEC Form 20-F reporting requirements in the ADR market attenuates the price discovery process in the home country equity market when the difference in information environment quality is large.

Understanding Customers' Intention to Seek for a Better Deal in Electronic Marketplace: The Role of Tolerance for Sacrifice Gap

ABSTRACT

Online consumers make frequent use of the Internet to search for product and price information. In this study, an online model is proposed and empirically tested in investigating the role of tolerance for sacrifice gap in understanding customers' intention to seek for a better deal. Data was collected through an online survey. Structural equation modeling was employed to test hypotheses. The results show that tolerance for sacrifice gap was not only a strong predictor of intention for continuing search but also itself being related to consumer product knowledge, perceived control, and consumer product involvement. Direct relationship between another construct “perceived reduction in sacrifice gap” and “intention to seek for a better deal” was also found. Theoretical and managerial implications are discussed.
