time_task

An oTree app for eliciting discount rates using intertemporal multiple price lists (MPLs). Subjects choose between sooner and later payments across blocks of time-dated options.

Features

• Multiple price lists: Intertemporal choices presented in blocks of rows
• CSV-driven instruments: Task configurations loaded from CSV files
• Multi-locale support: Separate configs for different locales (e.g., USA, RSA)
• Block structure: Questions organized into blocks (block_id) with configurable rows per page
• Randomized payment selection: One choice randomly selected for payment

Setup

Add to your oTree project and include in SESSION_CONFIGS:

SESSION_CONFIGS = [
    dict(
        name='time_preferences',
        app_sequence=['intro_task', 'time_task', 'final_page'],
        num_demo_participants=1,
    ),
]

Place instrument CSV files in configs/.
