Enhancing generalizability theory with mixed‐effects models for heteroscedasticity in psychological measurement: A theoretical introduction with an application from EEG data

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Generalizability theory (G‐theory) defines a statistical framework for assessing measurement reliability by decomposing observed variance into meaningful components attributable to persons, facets, and error. Classic G‐theory assumes homoscedastic residual variances across measurement conditions, an assumption that is often violated in ...

How iteration frequencies affect project uncertainty and risk ‐ An empirically elaborated model

Decision Sciences, EarlyView.
Abstract Iterative approaches have gained prominence in new product development (NPD) projects in response to increasingly dynamic and turbulent business environments. In this article, we study how iteration frequency—that is, the rhythm at which development teams revisit and test comprehensive products—affects an NPD project's uncertainty and risk. We

Broke Autocrats, Broken Elections: Trade Shocks and Electoral Fraud in Autocracies

Economics &Politics, EarlyView.
ABSTRACT We argue that when terms‐of‐trade (ToT) shocks reduce resource rents, autocrats lose the fiscal capacity to sustain loyalty through patronage and increasingly rely on electoral manipulation as a survival strategy. We present a simple model in which rents finance patronage in normal times, while adverse shocks reduce the effectiveness of ...

Rich Dad Poor Dad? CEO Private School Background and Firm Risk

European Financial Management, EarlyView.
ABSTRACT We examine the effect of CEO childhood socioeconomic status (SES) on firm risk. Using hand‐collected data on US CEOs' private high‐school attendance as proxy for high‐SES, we find that firms led by high‐SES CEOs exhibit 5.35% lower firm risk. This effect diminishes with CEO tenure, analyst coverage, and institutional ownership, consistent with

The Liquidity Sprint: Short‐Term Cash Needs and Access to Credit

European Financial Management, EarlyView.
ABSTRACT We identify the causal drivers of the COVID‐19 ‘dash‐for‐cash’ in Europe using a hand‐collected panel of Euro‐area firms (2018‐Q4–2020‐Q3). Exploiting regional infection intensity as an instrument, we find that a one‐unit EBITDA decline raised credit‐line utilization by 15.5 percentage points in 2020‐Q2. Unlike the US ‘fallen‐angel’ narrative,

Financial Statement Information and Equity Value: The Role of Real Options Characteristics

Financial Management, EarlyView.
ABSTRACT This paper examines whether firm‐specific real options characteristics are equity value‐relevant beyond valuation estimates anchored in financial statements. Using extensive historical data for the United Kingdom, we assess and compare the forecast accuracy and explanatory power for stock prices of equity valuation models based on residual ...

Speed Bump and Stock Market Quality: Evidence From NYSE American

Financial Management, EarlyView.
ABSTRACT Should trading speed of high‐frequency traders be regulated? Using the data from the New York Stock Exchange American, this paper examines the impact of a speed bump on market liquidity and price discovery. Our results indicate that the use of a speed bump can lower the costs of adverse selection through reducing informed trading.

Call-by-value combinatory logic and the lambda-value calculus

1992
Since it is unsound to reason about call-by-value languages using call-by name equational theories, we present two by-value combinatory logics and translations from the λ-value (λv) calculus to the logics. The first by-value logic is constructed in a manner similar to the λv-calculus: it is based on the byname combinatory logic, but the combinators are

Intersection and union types for combinatory logic and principal type-scheme for concurrent lambda-calculus

2020
ABSTRACT The aim of this work is mainly to study the principal type-schemes for terms of a parallel and non-deterministic Lambda Calculus in a type discipline which allows intersection and union types. In pVL Dezani-Ciancaglini et aL'93], {M. Dezani- Ciancaglini et aL'94] and [M.
