Quick answer: APSA format is the official manuscript style established by the American Political Science Association in the APSA Style Manual for Political Science (revised August 2018 edition, grounded in the Chicago author-date system). Standard APSA formatting requires 1-inch margins on all sides, double-spaced 12-point serif type (such as Times New Roman), left-aligned ragged-right text, sequential page numbers in the upper-right header, a maximum 12-word title, and a 150-word abstract placed directly on the title page or separate cover page for peer review.
Core Rules of APSA Formatting
Manuscripts submitted to political science journals—such as the American Political Science Review, Perspectives on Politics, or PS: Political Science & Politics—must adhere to strict layout standards. Professional apsa formatting ensures editorial consistency and supports double-blind peer review across empirical and theoretical political science scholarship.
The 2018 edition of the APSA Style Manual establishes the following mechanical specifications for all general manuscripts:
- Page Margins: 1 inch (2.54 cm) on all four borders (top, bottom, left, and right). Older print guidelines that required 1.5-inch margins for physical typesetting have been superseded by uniform 1-inch electronic submission margins.
- Typography and Font Size: A legible standard serif typeface—predominantly 12-point Times New Roman or Garamond. Use the identical font and size throughout the title page, main body, block quotations, and reference list.
- Line Spacing: Double-space every section of the paper, including block quotations, footnotes, table notes, and reference entries. Do not insert extra blank paragraph lines between paragraphs or sections.
- Paragraph Indentation: Indent the first line of every body paragraph 0.5 inches (1.27 cm) using the word processor’s ruler or paragraph formatting settings, rather than inserting manual spaces.
- Text Alignment: Left-aligned text with a ragged right margin. Do not justify the right margin, as full justification introduces irregular word spacing that interferes with automated layout software.
- Pagination: Arabic numerals positioned in the upper-right corner of the header, flush with the right margin, typically 0.5 inches from the top edge. Page numbering begins on the title page (page 1), although some journals request hiding the page number on the initial cover page.
APSA Title Page and Cover Page Structure
The apsa title page functions as both an executive overview and an administrative divider. In professional submissions, authors must often produce two versions: an unblinded apsa cover page containing full author identification for editorial tracking, and an anonymized manuscript file for blind review.
Unblinded Cover Page Elements
When preparing an unblinded title page for initial editorial intake or seminar presentation, arrange the following components centered on the top half of page 1:
- Manuscript Title: Set in headline-style capitalization, bold, 12-point type. The APSA Style Manual specifies that titles and subtitles combined must be concise—strictly 12 words or fewer. Separate subtitles with a colon, never an em dash.
- Author Information: Author full name, institutional affiliation (department and university), and corresponding email address.
- Author Note / Acknowledgments: An asterisk (*) following the title links to an author note at the foot of the cover page detailing funding support, institutional review board (IRB) approvals, data repository identifiers, and gratitude to seminar participants.
- Word Count: An accurate total word count (including abstract, notes, and references) placed below author affiliations.
Anonymized Title Page and Abstract
For double-blind peer review, strip all identifying author information, institutional affiliations, and self-identifying grant numbers from the title page. Center the title at the top of page 1, followed immediately by the heading Abstract.
The abstract must not exceed 150 words. It should concisely summarize the core research question, theoretical framework, empirical methodology (such as regression discontinuity, comparative case analysis, or survey experiments), key empirical findings, and substantive implications for political institutions or public policy. Below the abstract, list 3 to 5 keywords separated by semicolons to facilitate scholarly indexing.
APSA Paper Format and Heading Hierarchy
The standard apsa paper format uses a three-tier heading structure to organize research articles into logical subdivisions. Headings must remain parallel in phrasing, avoid direct repetition of body sentences, and refrain from numbering schemes (such as 1.0 or 1.1) unless specifically mandated by a specialized quantitative venue.
Heading Level Specifications
- Primary Headings (Level 1): Centered or flush left, set in bold type with headline-style capitalization. Used for major structural sections: Introduction, Theoretical Framework, Research Design, Empirical Results, Discussion, and References.
- Secondary Headings (Level 2): Flush left, set in bold or italicized type with headline-style capitalization, placed on its own line above the subsection paragraph.
- Tertiary Headings (Level 3): Left-indented 0.5 inches, bold or italicized run-in heading ending with a period. Body text begins immediately after the period on the identical line.
Citation Mechanics and Explanatory Footnotes
In-text parenthetical citations follow the Chicago author-date convention without a comma between author and date: (Nokken 2024) or (Hellwig and Nokken 2025, 114). For detailed citation templates spanning monographs, edited volumes, and government documents, see the companion guide on APSA citation mechanics.
APSA format reserves numbered footnotes for substantive explanatory commentary, institutional qualifications, or supplemental model specifications that would disrupt the narrative flow. Never use footnotes for routine bibliographic citations. Place superscript Arabic numbers after punctuation marks, and double-space all footnotes at the base of the corresponding page.

Coalition Durability Under Fiscal Shock: Legislative Cohesion in Decentralized Cabinets
Abstract
How do unexpected fiscal shocks alter coalition cohesion in multi-party parliamentary systems? While prevailing theories emphasize ministerial portfolio distribution, few account for subnational fiscal stress. This study evaluates coalition survival across 24 regional governments between 2008 and 2022. Using a generalized difference-in-differences design, we find that unanticipated revenue contractions increase coalition termination hazards by 34 percent, primarily driven by junior coalition defections over entitlement expenditures. These findings clarify how decentralized budgeting constraints reshape executive stability in fragmented legislatures.
Keywords: coalition governance; legislative bargaining; fiscal federalism; parliamentary stability; cabinet duration

Coalition Durability Under Fiscal Shock: Legislative Cohesion in Decentralized Cabinets
Introduction
Cabinet dissolution remains one of the central hazards of parliamentary governance. While institutional scholars have identified vote-of-no-confidence mechanisms and cabinet veto points as primary determinants of government duration (Vanderbilt and Ramirez 2021, 88), macroeconomic disruptions frequently disrupt bargaining equilibriums. When subnational entities experience sudden revenue contractions, ministers face acute trade-offs between programmatic fidelity and coalition loyalty.
Theoretical Framework and Hypotheses
Legislative bargaining models assume that coalition partners maximize policy payoff alongside office-seeking goals (Alvarez 2019, 402). When exogenous revenue shocks occur, the fiscal surplus required to sustain inter-party compromises evaporates.
Fiscal Asymmetries in Junior Portfolios
Junior coalition partners with specialized ministries—such as labor, education, or public health—experience disproportionate electoral penalties when compelled to endorse retrenchment packages. Consequently, we hypothesize that junior party defection rates rise sharply following municipal debt distress.
Empirical Design and Methodology
To test this proposition, we examine administrative budget datasets spanning subnational legislative assemblies, evaluating how primary research data and legislative roll-call records reflect coalition strain.
Econometric Specification. We estimate cabinet survival through a semi-parametric Cox proportional hazards model, stratifying by parliamentary term and controlling for chamber fractionalization.
