Jar Theory Development

name: jar-theory-development
description: Use when building the economic mechanism and deriving signed, falsifiable predictions for a Journal of Accounting Research (JAR) manuscript — grounding hypotheses in information economics, contracting, and disclosure theory rather than psychology-style construct chains. Builds the mechanism; it does not design the empirical test (jar-methods) or run it (jar-data-analysis).

# Theory & Prediction Development (jar-theory-development)

## When to trigger

- Predictions are descriptive ("X is associated with Y") with no economic channel
- A referee asks "what is the mechanism?" or "why would a rational agent do this?"
- The sign of the effect is ambiguous and needs an explicit argument
- You need to motivate an empirical prediction from an analytical/agency model

## How JAR theorizes: economics first

JAR's dominant tradition is **positive, economics-based** accounting research. Predictions are derived from the behavior of informed economic agents — managers, investors, analysts, auditors, regulators — under asymmetric information, contracting frictions, and proprietary costs. The relevant toolkit is **information economics** (signaling, disclosure, adverse selection), **agency/contracting theory** (incentives, monitoring, debt covenants), **market price-formation** logic (how information enters prices and expectations, in the Ball-Brown lineage), and **standard-setting/political-economy** arguments. This is *not* the latent-construct, mediator-moderator style of psychology-based fields: a JAR mechanism is an economic argument about incentives and information, often disciplined by a simple model.

## Build the mechanism

- **Name the friction.** Information asymmetry between whom and whom? A contracting incompleteness? A proprietary cost? The friction is what makes accounting information matter.
- **Specify the agent's problem.** What does the manager/investor/auditor maximize, and how does the accounting variable change their optimal action or belief?
- **Sign the prediction.** State the predicted direction and *why*. If two channels push opposite ways (transparency vs. proprietary cost; recognition vs. disclosure), say so and let the data adjudicate — an ex-ante ambiguous sign is acceptable if argued, but it must be argued.
- **Derive observable implications.** Beyond the main effect, predict **cross-sectional variation**: where should the effect be stronger (high information asymmetry, weak governance, binding covenants)? These conditional predictions make the channel testable and separate it from alternatives.
- **Consider a model.** Analytical work is welcome at JAR; a stylized model that yields the comparative static you test sharpens the prediction and pre-empts "story-time" critiques.

## Registered Reports note

On the **Registered Reports** track, the theory and signed predictions are locked in the **Stage 1 protocol** before data are seen — strong a priori derivation is essential because in-principle acceptance is granted on the protocol's quality, not the eventual results.

## Checklist

- [ ] The friction (information asymmetry / agency / proprietary cost) is named explicitly
- [ ] The agent's optimization problem and the accounting variable's role are specified
- [ ] Each prediction has a stated sign and an economic reason (or a justified ambiguous sign)
- [ ] Cross-sectional / conditional predictions sharpen the channel
- [ ] Alternative (non-causal or mechanical) explanations are anticipated
- [ ] If analytical: comparative statics map to the empirical predictions

## Anti-patterns

- **Construct-chain theorizing**: psychology-style mediators with no economic agent or friction.
- **Sign by hand-waving**: predicting a direction with no incentive argument.
- **Kitchen-sink hypotheses**: many associations, no unifying mechanism.
- **Mechanism only in the title**: a channel asserted in the intro but never tested cross-sectionally.
- **Rational/behavioral muddle**: invoking efficiency and mispricing interchangeably without committing.

## Output format

```
【Friction】information asymmetry / agency / proprietary cost (between whom)
【Agent's problem】who maximizes what; role of the accounting variable
【Main prediction(s)】sign + economic reason
【Conditional predictions】where stronger/weaker (and why)
【Model?】comparative static derived / not needed
【Alternative explanations to rule out】[...]
【Next step】jar-literature-positioning or jar-methods
