Exploring ethnic consumer response to crossover brand extensions

This research uses a social identity theory approach to investigate the impact of cultural identity on ethnic consumer response to ethnic crossover brand extensions—brands associated with one ethnic group that crossover into a product category associated with another ethnic group (e.g., McDonald's Café con leche). Study 1 demonstrates that the manner in which crossover brand extensions blend ethnic consumers' in-group and out-group cultural representations impact brand extension cultural fit and parent brand attitudes, and perceived ethnic target market impacts brand extension attitudes. Study 2 demonstrates that high ethnic embeddedness extensions strengthen ethnic consumers' self-brand connections. These findings provide managerial implications for practitioners considering a crossover brand extension strategy.     

Differences in measures of the fiscal multiplier and the reduced-form vector autoregression

The literature has recently asked whether the effects of fiscal policy vary with the state of the economy (Christiano, Eichenbaum, and Rebelo 2011; Rendahl 2014; Auerbach and Gorodnichenko 2012). We study this question in the context of vector autoregression (VAR) estimation. We show formally that, if (asymptotically) the parameters of the reduced-form VAR differ, then the dynamic effects of fiscal policy differ as well, generically and for any set of identification assumptions. Thus, in theory, the econometrician can detect these differences (either across time or space) generically just by relying on reduced-form VAR estimation.     

The crossing of physical boundaries: de-materialization and the move towards de-collecting

ABSTRACT

The tension between materiality and liquidity in society provides a promising opportunity to elucidate how de-materialization influences the iconic transfer of meaning from a singularized physical object into alternative formats of experiential consumption. We conducted in-depth unstructured existential-phenomenological interviews with physical book de-collectors. We investigated the role of imagination in maintaining a connection to the de-materialized collection and its impact on the person–object relationship. When consumers de-materialize a collection of physical books, they confront their values related to materiality and emotional physical attachment while opening the possibility of sharing and undergoing new experiences that can transform their relationship with singularized objects and with other human beings. De-collecting represents a way in which consumers can maintain indexical connections to singularized objects’ meaning while letting the physical item go.     

MEASURING PRODUCTIVITY

Abstract Quantifying productivity is a conditio sine qua non for empirical analysis in a number of research fields. The identification of the measure that best fits with the specific goals, as well as being data driven, is currently complicated by the fact that an array of methodologies is available. This paper provides economic researchers with an up‐to‐date overview of issues and relevant solutions associated with this choice. Methods of productivity measurement are surveyed and classified according to three main criteria: (i) macro/micro; (ii) frontier/non‐frontier and (iii) deterministic/econometric.     

Accounting Ratios and the Cross‐section of Expected Stock Returns

Under clean‐surplus accounting, the log return on a stock can be decomposed into a linear function of the contemporaneous log return on equity, the contemporaneous log dividend–price ratio (if the stock pays a dividend), and both the contemporaneous and lagged values of the log book‐to‐market equity ratio. This paper studies the implications of this decomposition for the cross‐section of conditional expected stock returns. The empirical analysis reveals that the log accounting ratios capture cross‐sectional variation in both the conditional mean and conditional variance of log stock returns, which is consistent with the decomposition. It also brings fresh insights to the relation between firm size (market equity) and conditional expected stock returns. The evidence indicates that the conditional median return increases with firm size, while the conditional return skewness decreases with firm size. Empirically, the skewness effect outweighs the median effect, leading to the well‐documented inverse relation between size and average returns. The results of out‐of‐sample tests suggest that investors could use the information provided by the observed values of the log accounting ratios to formulate more effective portfolio strategies.     

Judicial checks on corruption in the United States

Judicial oversight provides an important check on executive and legislative power. Two components of judicial oversight have been identified in the literature: judicial independence and constitutional review. Recent research using country-level data indicates that the effectiveness of constitutional review is largely determined by the rigidity of the constitution. In this paper, I use state-level data to test whether judicial independence and constitutional rigidity are related to a specific type of abuse of power by government officials: corruption in office. Specifically, I fit negative binomial regressions in which the dependent variable is the number of officials convicted for corrupt acts and the independent variables are (i) measures of judicial independence, such as judges’ remuneration, method of appointment, and term length, along with various controls or (ii) measures of constitutional rigidity, such as legislative majorities required to propose constitutional amendments and provisions for constitutional conventions or constitutional initiatives, along with various controls. I find that, in general, states with higher levels of judicial independence and more rigid constitutions have lower levels of corruption per capita than states with the opposite characteristics.
